Your conclusion generalizes to no-charge software, not to all FOSS. The "free" in FOSS stands for free software, meaning free as in freedom rather than free as in price.
If a program is free software [1] then a user of the program can read the source code, modify it, and distribute (including sell) unmodified and modified versions of the program/code. A user who lacks the program or the code isn't entitled to the freedoms but can get the software from someone else who has it.
Developers of free software can charge for it. One way of making money from free software is charging for access to the developer's server. Another way is charging for more expansive user support. (Alternatives to charging for the software itself include requesting donations and selling physical merchandise.)
You say developers of free-as-in-libre software can charge for them, but in practice any developer that tries to sell his free-as-in-libre software will be viciously laughed out of the room by everyone else.
The F in FOSS in practice stands both for free-as-in-libre and free-as-in-beer. And you don't get to talk about the quality of free beer.
Linux however demands me to do the computer, it doesn't enable me to do anything because I'm too busy doing computer bullshit. This isn't necessarily surprising, since the goal of Linux (more accurately FOSS) is to use FOSS and isn't concerned about what I need/want to do.
So no, most people (or at least myself) will not move from Windows to Linux. I use computers to do things, not preach the holy scriptures of FOSS.
Linux's interface is still archaic compared to windows 7 unfortunately.
I'm amused that I find myself preferring Windows 11 Explorer with its bloody worthless context menu and taskbar to anything FOSS has to offer.
GNOME? It's sincerely cancer. KDE? No software actually uses it. xfce/LXDE/et al.? Look, I'm not going to use a GUI that demands I go CLI some plain text files to change settings.
Getting video crashless seems hard, I had problems back in 2006. Have not tried again.
FOSS's primary problem is that the goal is the tool itself, rather than what is done with the tools: Commercial software exist to let the end user achieve something, which in turn generates profit for the commercial developers. FOSS exist to let the FOSS developers achieve their dreams, end users be damned.
A video editor crashing every hour is a problem for the end user, but if the FOSS developer doesn't care then that's that.
This is why Photoshop will continue to surpass GIMP, and why exceptional FOSS like Blender succeed where other FOSS do not.
This is why I really dislike the term "FOSS". It's both redundant and erroneously misleads people to thinking things like this. Free Software can absolutely be developed under contract, in which case yes, you are entitled to the developers time under the terms of the contract.
When you buy something, you are exchanging your money to obtain someone else's time. In this case, time that someone else spent to make sure a program works.
The F in FOSS stands for free, so nobody is under any obligation to spend their time so you don't spend yours.
