Definitely not the same telemetry collected for W10 as there is for W11, and W10 ran great compared to the dumpster fire that is W11 even today 4 years later. Windows 8 was not remarkable and arguably the most forgettable release to date.
Bazzite isn't a fork of SteamOS, it's a fork of Fedora Atomic that runs an interface similar to SteamOS. I'm also curious to hear what improvements it brings over actually running SteamOS on the Deck?
It's not because Windows 11 is superior, it's because users are being forced to Windows 11. Either through threats of EOL of Windows 10 or just enshitification of Windows 10 by latest updates.
The vast majority of "normal" computer users I know don't want windows 11. Not because its bad or they changed the hardware requirements. Its because they like windows 10 better and are comfortable with it. And that they are being forced to windows 11 makes it worse for them. Especially if their PCs are running fine for them. I tell them about 0Patch and Extended Security Update Program. If they have to install windows 11 on their "non compatible" hardware I will help them use rufus.
