Linux

I have a raspberry pi as a print server but that’s about it. I tried a few distros on an old laptop but none really worked that well.

Arch on every box in the house, including the primary router. Mixed Intel and AMD. Openwrt on every AP (unfortunately Mellanox and MediaTek firmware blobs for the radios). GrapheneOS on my daily and LineageOS on my legacy phone.

Aside from occasional games, I don't install anything I don't have the source to. My phone is the only exception, for apps required to interface with the rest of the world.

Mostly FOSS locally, but I rely on some proprietary software where there are gaps in the FOSS ecosystem.

Increasingly so over time. Will try to install coreboot on my laptop soon. I avoid proprietary blobs where possible too but for stuff like the kernel, proprietary blobs are kinda unavoidable if you want a fully functional system. Tbf I've not tried linux-libre but I just assume it won't agree with some of my tower PC's hardware.

Aside from low-level stuff, I do still use Steam (and the proprietary games on there) and Discord—Steam cause all my games are there and it's convenient, and Discord cause a few of my friend groups primarily talk over Discord. Been considering setting up a Matrix bridge for Discord but I don't think that meaningfully achieves anything since it'll still all be on Discord's servers which are proprietary. I also occasionally install proprietary software to read proprietary file formats and would usually uninstall once I'm done reading the file.

FOSS for everything on my laptop and server, except discord and Spotify, but I’m migrating away as much as possible. I have a Pixel 7 with GrapheneOS and use mostly FOSS there too, but have Google play installed to the sandbox for some social media apps. Not perfect but pretty good and improving

I wish it was more, but the paid/closed options in a few categories are just significantly better than anything foss
