I honestly fully believe that proprietary software is bullshit and all software ought to be Free Software. I’m not saying I don’t use proprietary software, but I don’t trust it. If I run proprietary software, I go out of my way to try to run it in prison. I don’t let my Nintendo Switch connect to the internet except when I have a very specific reason and then I disconnect it immediately after I’m done. When I bought a robot vacuum cleaner, I bought specifically the model that I knew I could hack to not phone home. I bought a phone on which I could run LineageOS without the Google apps. (And, yes, I’m running a proprietary EFI BIOS on my main desktop machine and such. But I do take a lot of steps to limit how much influence proprietary software has on me and my devices.)
