I think there’s a difference in personal interpretation of what a “Linux issue” is, here. It sounds like you might be interpreting “Linux issue” as problems with the software itself, or its capabilities, features and processes etc. Personally, I am using “issues with Linux” to mean the entire user experience from start up to using the GUI and whether or not I can do the things I want and need to do on a daily basis easily and intuitively. Certainly, Linux as a software plays into it, but the things you are brushing off as 3rd party incompatibilities are absolutely part of the Linux experience in my opinion. I’m not trying to throw blame, but when introducing new people to Linux it’s best to acknowledge there may be some tinkering and adaptation needed to get things working as they should.
I’ve been tinkering with my Linux machine for the past 8 months or so, and having random issues like the ones I listed and more besides that I’ve already solved. Meanwhile my old Windows 7 machine has been working flawlessly for about 8 years, no regedits or crap software issues. I think I had a driver issue with my mouse a couple years ago that I clicked a button and it fixed it. My laptop running Windows 7 also has been working flawlessly since about 2016 beyond prompting me to format media that I connect to it, but I press a button and that goes away. Recently I’ve been having compatibility issues with software because it’s such an old OS but as you said, that’s a 3rd party software issue, not a problem with Windows 7.
Glad your Linux experience is so smooth though. Must be nice!
