Yes and no.

let’s say I have a website that hosts user generated content like a forum or something. Some other person just hosts a mirror of my website that is not under my control. If some user requests me to delete his data, I can do that. i cannot delete the data from the mirror site.

Nothing else is happening in the fediverse. The only difference is, that in the fediverse the license and technology is set up to encourage mirroring content.

I‘ve had this issue on several distros and multiple friends have the same issue. Video hardware acceleration in a browser is a mess. This is definitely not only affecting me as there is a significant amount of complaints on forums and reddit.

And there is no way that the average computer user will use arch. And as long as you gotta fiddle around with your system to get even the most basic shit running smoothly like watching a high resolution youtube video and moving around windows on your other screen at the same time linux will stay irrelevant as a desktop os. It‘s still a system for nerds and I kinda feel like that this is okay.

Your first point is web browsing. Even that doesn‘t work properly on a linux desktop lol. Browser performance is abysmal because the browsers lack out of the box support for hardware acceleration. Even if you get it to work it might not work reliably and an update might break it again.

Try using a discord call and open a youtube video in 4k at the same time on a a freshly installed linux desktop. The audio will be choppy and the video will drop frames like crazy. Just moving around windows on your desktop is not nearly as smooth as it is on windows.

I’m currently running Mint on my Computer and Ubuntu on servers.
