I’ll start: printers.
I bought an HP in March 2020 when my job went remote and HP bricked it remotely after only 100 pages because I wouldn’t sign up for their subscription program. Ended up trashing a perfectly good printer.
Luckily my library’s close by and I can print there remotely.
There is some open source software that is associated with Facebook, like compression with Zstandard, a very common and useful compression format. Don’t care that it’s from them in that case.
