TL;DR there was a backdoor found in the XZ program. All major distros have been updated but it is recommended that you do a fresh install on systems that are exposed to the internet and that had the bad version of the program. Only upstream distros were affected.
Yeah, just never be a dissident, or a whistleblower, or an activist, or a member of a vulnerable marginalized group. Remember, if you obey there’s no reason to fear being spied on.
I really don’t think you understand how serious this kind of backdoor is. It puts certain people in real danger.
