Ieft leaning? These orgs sound more like the typical liberal right centrist orgs from america lol

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.

This type of attack theoretically also works with signal or telegram or whatever message service that works entirely without a phone number.

Why would you use first party messaging apps? Who the hell still sends sms? Just use signal. Easy fix.

You cannot really un-opensource software very well.

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