Wow. I couldn't possibly be any more your opposite in this regard. I try very hard not to run proprietary software. For safety reasons. And when I do run proprietary software, I do my best to sandbox it. I don't let my Nintendo Switch talk to my home network often. I hacked my robotic vacuum cleaner not to phone home. I do my (U.S.) taxes on stupid paper because there aren't pure-FOSS options for filing electronically.
