Again, it's just one example. Others are far worse: try to figure out how to play a song or some other audio into a skype call by piping data directly into the mic input channel. It's pretty trivial in windows, and there are third party tools with easy to understand GUIs if you can't figure it out on your own. On Linux you'll be futzing with jackd configs for hours.
I don't like arbitrarily changing UX either, but it's not like Windows doesn't have that problem. I had massive switching headaches moving to the new "ribbon" based stuff in Microsoft Office.
Of course neither side is perfect, but I am thoroughly unconvinced by the "unusable" argument. THere are definitely biases with ignoring the headaches that Windows forces upon users.
For your first example ctrl double swipe on my trackpad works pretty much everywhere and ctrl +/- works everywhere except my terminal where ctrl-shift +/- does the job.
As for your second. This is not a common use case that any non-technical person would even think of trying. If you needed to I would suggest ignoring jackd (whatever that is) and using the gui for pulse audio control.
The second example is used by people who play video games all the time. People do it for skype/ventrilo calls during gaming sessions constantly. It may not be a common use for _for you_ but it is not as rare as you appear to think.
But at least I can ssh into their rigs after the fact and fix them remotely. Trying to get them running teamviewer every time there is a problem on Windows is a nightmare.
Also consider the #1 reason I get called is because people install some virus or spyware or clickjacker by clicking and running random stuff off the Internet. On any Linux based distro none of that stuff works so what ends up happening is my repeat customers every 2-4 months are Windows users and the dozen or so clients I have using some flavor of Ubuntu might email me once a year like "can I run X?" and I just go look on playonlinux if its supported or not. Libreoffice opens all the old Doc and XLS files fine, their printers work, their wifi works, they can use their crappy 1995 webmail client from their ISP no problem, and they even get neat perks like having their phone rings show up in their desktop notifications if they use KDEConnect.
My experience is that there is no substantial difference in the amount of "fucking around" you have to do with Windows or Linux. I had to install custom graphics drivers from third party sites, install custom keyboards, mess around with random settings, especially after upgrades between different OS versions.
Please show me an actual study instead of talking about personal anecdotes.
I do not think you are truly interested in changing your mind.
