Long one...
Freeware game developers.
I have been around a lot. Been in and out of my different spaces and sectors in software. From projects worth over a billion to projects I do for free. Free as in beer, speech etc.
I am in the belief that if you do something out of passion and love and give it away for free, that you have done just that. You have done it for the love of doing it and shared it with others so they may enjoy it to.
However... for whatever reason, I'm trying to work it out, the gaming community, especially modders and "content creators" are an entirely different kind of bunch.
They seem to be stuck in the good ole days of bulletin boards and mail-order shareware distribution.
They seem to think that when you publish your game modification or addon to the public, without license and without restriction, under "default copyright" mechanics that they can still retain control over the distribution and make statements about how the end user should "Download", "Install", "Use", "Share", "Copy", "modify" their works.
Not only that, but they become fairly toxic about it too.
I gather very few of them are in anyway professionals. I also gather a lot of them are basically just kids.
Recently while playing a game, I went off to find some "quality of life" automation mods to enhance my game. I googled, browsed and downloaded 4 or 5 mods.
I ran the game and up pops a message
"DONT USE SCUMMY DOWNLOAD SITES" - OK
Now, I'm a bit of an old git and often a stickler for details.
This is shouting at me. Yes? It doesn't have a source. It's an anonymous popup. It doesn't tell me what mod is sending the message, it doesn't tell me what site its referring to, so I can't exactly action it, can I? I mean, even if I wanted to after it's basically chastised me for some implied infraction of where I downloaded their mod from!
Researching into this and oh boy did I uncover a rats nest of little bitches.
It turns out the modder in question is absolutely proud of his message. He says it should include swear words and be far less polite to the user as apparently there are some of these 3rd party mod distribution sites that he doesnt like.
My 7yo kid plays this game. They still didn't see this as an issue.
At one point the modder mentioned that he has considered ... wait for it... deleting all of the users save games and backups of in the event he discovers his mod was downloaded by a website the doesn't like.
I was quick to ask him politely, for his own sake, not to do that. In the UK that would 100% be criminal miss-use and while I doubt I would get him in court I would certainly put a bit of effort and even money into making sure his life is shit for a while.
Anyway, you just don't do this stuff, really.
If you give your work away for FREE and publish it on a PUBLIC github repository without attached, embedded, implied or referenced license.... you HAVE NO CONTROL OVER IT. You have no control over the distribution, you have no control over the users or how they use it. "Default copyright" does, technically prevent these mod sites from sharing on your work, but as it's "FREE" and has already been freely distributed to the public at large.... no copyright lawyer or court will go near it with a barge pole. Especially when there is zero actual "worth" involved.
I have released freeware game mods and utilities. They were further distributed by 3rd party sites. In fact one was downloaded about 10 times more from them than from my site. Did I get upset? No. Did I complain, No. Why? Well, I wrote it for me, I wrote it because I enjoyed it. I figured others might enjoy it too, so I published it for free.
I have no silly little notions that I can control that software or that I can make any requests or demands of the users. I am fully aware that any attempt for me to, after the fact, say, "Oh wait, I don't want you doing X", would be stupid, childish and fruitless.
EDIT:
A side I hadn't considered and I don't think "they" have either. This particular modder has a dozen or so "contributors". They share PRs and code in the repo.
Now given there is no license involved here, no OSS license, no GPL-like, not even a custom license of a boiler plate one from ChatGPT.... Should the repo owner decide make all his repos private, to bundle it all up and sell it to the game publisher for lots of money... those contributors will be right up shit creek without a penny in the deal.
Worse, even now there would be "worth" in it and a lawyer might be interested in fighting their case ... it is extremely unlikely, under the license conditions they would be able to get any damages for the mod "maintainer" from just selling the work without giving even credits.
I note this has happened before, can't remember which game, but a very popular mod got "bought" into the main game by the publisher. Wars errupted as the owner of that mod had received hundreds of submissions from contributors and he paid exactly none of them a penny.
EDIT 2:
My rather petty response to all of this was to make a small statement as a shot across the bow.
I forked his repo and modified the message to say something nice like, "Please be kind to each other".
It's a small slap in the face to him and a reminder of where and how he published it, permitting me to do as I did, while at the same time violating his "default copyright" blatantly in his face. Just to reminding him of it's true worth.
EDIT 3:
Trying to offset myself to a different point of view in aim of fairness.
To me, a professional software engineer for 20+ years the amount of software I have written is effectively HUGE. To me a little evening project for a few dozen hours and releasing a game mod or util is a tiny fraction, a literal throw away, "here you go, thank you".
To an amatuer game modder, who probably has zero professional experience in software or tech, those few thousand lines of LUA code in his mod amounts to a sizable portion of all the software he had written. The fact that thousands and thousands of people download it and use it must make him feel really proud.
I can understand that they might see their repo as being worth far more than it is, while at the same time not having the faintest clue and being poorly advised on the need for and purpose of a license.
The thing is. If they were not so petty, ignorant, childish, and annoying about it (little bitches) they could be educated, informed and things explained to them about how modern "FREE" software distribution does not just imply it's "FREE at time of access", it means its FREE as in speech, as in beer. FREE to do with as you please without restriction or warranty.
Some one strawmanned the analogy of a YouTube video to me. It's freely available to the public, does that mean you can do what you like with it, including uploading it to other websites and gain ad revenue?
Well for a start that has been done to me. YouTube detected it and submitted the copyright take down request automatically.
Why is this different to the mod case? It's because YouTube videos are protected by both a license with TEETH and have a body backing that license with enough power to scare others into compliance.
The GPL and GPL-like license (and others) may not provide quite as aggressive protection as YouTube license and copyright system, but in extreme cases they can and do find money to help represent license holders works.
