Its been a very long time since I've used any Adobe software, and I do graphics related stuff all the time. I use Linux (but most FOSS programs are available on Windows, Mac, etc. too now) and free tools like Gimp, Inkscape, and many others.
It's possible that at some point I may need to use commercial products again so I keep the old master disks around, in case I ever need them (upgrades are usually cheaper than buying new) but I have not had any of it on my machines or used any of those apps in - more than a decade now. When I have had to share files back and forth with users of those apps, we've always figured out a way to get whatever data we needed to one another. Some format which we both have.
Unfortunately, the state of CAD software on Linux is not quite as developed as the tools on Windows. But I just have never needed CAD so much that I couldn't make do with what I've got access to.
So far, it does what I've needed it to do. (Just little things)
If I was a professional like a mechanical engineer, or architect or industrial design pro then I likely would shell out the big bucks to buy the high end CAD tools, and deduct the cost from my taxes.
If I were those companies I would offer free versions with basic functionality for non-commercial users, not just college students. It would be a good business practice.
Both are cases of dominant market leaders doing whatever they please, knowing full well most people are going to have to take it. Adobe software is the defacto standard in graphics and Solidworks in most sectors where CAD is a thing.
Even worse is that you don't really get value for money as development is slow or non-existent. Some shiny features are occasionally tacked on, but at its core it's still the same software that can throw a hissy fit over nothing. Engineers have learnt to tiptoe around the peculiarities and ways simple operations can throw errors but that really shouldn't be necessary for something that costs this amount of money, and each year too.
Apparently Fusion 360 isn't enough of a threat to change things. It's a deal with the devil too, as it's not just Autodesk but also a cloud solution. Maybe getting shafted by Dassault is still better.
