No, not "just as equally". I've checked and it is very rare for a Windows fanboy to intrude into a discussion forum or article about Linux. Not saying it never happens, but it is pretty rare.
I think it is mostly because most Windows users aren't fanboys, so they can't be arsed to get into an argument over it.
Ah, "you've checked". Some of us have lived it, as actual users and occasional developers who are around such discussions. Trolls make sport of it everywhere. Few last long in any places of serious discussion, no matter which side they're attacking.
But that is exactly the same in the Windows world. I completely agree that Acrobat Reader is a fat, ungodly mess, and I hope never to use it again. But I would point out that it isn't paid-for software, so I'm not sure where we are going with this.
I made that clear - Acrobat was the same fundamental code base as Acrobat Reader. Had they tried to offer that as a paid option for Linux (I seem to recall they did not), it would have fallen flat on its face as a worthless joke just as their free offering did. That is not the fault of the platform or users, and yet it is the latter you continue to blame for companies not offering products.
Anyway, I believe that the Linux desktop culture of expecting software to be free discourages the corporate developers, because they must answer to shareholders, and that pretty much precludes them working for free. And thus we have a shortage of high quality desktop software.
And I know that the lack of proprietary software prevents people from purchasing it. That is not a cultural problem, because there cannot be a culture of not purchasing something which doesn't exist.
I'm sure there would be less uptake of proprietary options such as Acrobat, Photoshop, Microsoft Office, and so forth should they be offered in a competent, usable form. That will be partially due to users who, to use your pejorative terms, are 'religious', but in large part due to the lack of capture. People already on alternative platforms are no longer the ignorant newcomer, taking bundled software with the OS or computer package as it comes. They've seen they have choices, have made some already, and will continue to make them for their own reasons - cost, familiarity, usability, compatibility..
As for me, well no, I haven't always wanted to do every job I was given. But I honestly think that my professional pride motivated me to do something pretty close to my best, even when I was less than enthused about the task. I don't think I'm much different from most employees working in the field of their choice.
And by your professed age I would expect that naïveté to have been thoroughly vanquished..
