Linux

The only point I can really agree with you on here is Adobe products (and some other niche proprietary stuff like AutoDesk -- I don't consider MS Office an industry standard and if your job does I'm very sorry). And that's just corporate lock-in, if you're already paying hundreds of dollars a year to use those programs then yeah you're gonna stay on the corporate OS.

Other than that, everything you brought up just isn't quite accurate, or evaporates as you get more comfortable with the Linux ecosystem. The distro point, for example: every distro is just a starting point. Outside of some niche exceptions like Gentoo and NixOS that will radically redefine how you configure the system, any distro can largely be made to work similarly to any other. The major differences are just a) initial package set, b) the package manager, and c) the set of available packages. There is no one-size-fits-all answer to "what software should be on a computer", which is why there are so many distros and spins out there.

I would say gaming is actually pretty close to perfect, provided you don't play any of the games that have decided they just will never work on Linux -- almost exclusively games that use invasive kernel-level anti-cheat software which I wouldn't want to install on Windows either. There are a handful like Fortnite and Apex Legends which use EAC, which works great on Linux now, but the devs explicitly decided to disable it. Just like the corporate lock-in point, if you're committed to those games stay on Windows. Heroic and Lutris take a few more clicks to set up than Steam's one-click magic, but it's generally pretty straightforward for any game with any popularity.

The point about ads is where I start to think you're deliberately being obtuse. You think that, what, a splash screen telling you how to use your computer when you first boot it, and notifications from apps you installed, are advertising? And you find them similarly annoying as the actual sponsored content that shows up in your start menu, on the lock screen, in Edge, when you use Cortana... Not to mention the constant pressure from the OS to use those things? The only way I can interpret this without you just trolling is that you've spent too long in the Windows ecosystem and you've just adjusted to not notice how often it's shoving something in your face.
