I love Linux, but I never expect it to be mainstream or even extremely accessible to typical users. In fact, if it made it to mainstream, it’d probably get ruined somehow by corporate interference, monetization, etc. How you may ask? Well, corporations have a lot of money and influence and I’m sure they could “find a way” if motivated to do so.
They probably meant “everything that they use it for”. Like, in my case everything on Linux works for me, but I don’t play multiplayer games or use Photoshop. I have a single old monitor that can’t do HDR. I don’t watch Netflix. To be fair and pedantic, not everything anyone could possibly ever want to do works on Windows 11, either.
