I also run a lot of proprietary stuff like Discord or Instagram due to peer pressure but I let it slide and put my hopes on Android sandboxing the apps and GrapheneOS tweaks. In my opinion, making sure that proprietary app can’t reliably access your data and never giving it anything sensitive yourself is a decent risk model.
The only proprietary software I use and somewhat trust is Obdisian. Honestly, it’s just excellent and I can’t see myself moving away from it anytime soon.
I’ve recently had so many random freezes of the system, hangs on shutdown, panics on shutdown, freezes in system updates, that hard reset became a thing I did several times a day. Yet there were no systemd logs, nothing in dmesg, literally zero information on what happened.
I was skeptical in blaming Nvidia because at this point it became a Linux chiche, but then I started to switch to integrated graphics (disabling dGPU) and all of the problems miraculously went away.
