I’m a big privacy and FOSS advocate so my list is kinda long, but the main ones are:
-> Google (I use GrapheneOS)
-> TikTok
-> Tesla (too much data collection)
-> Microsoft (self explanatory, however for some things I need to keep an w10 LTSC VM configured)
-> Adobe (same reasons as Michaelsoft)
-> OpenAI (same reasons as Michaelsoft, but I do use it inside a vm in no-account mode for some work related things)
-> Uber (oh man that app is digital herpes)
-> Spotify
-> Facebook/Meta
-> Dropbox


As a Libertarian Lemmy user, I sympathize. I find it strange how there is a general ethos here that if you don’t agree with the left/“communism”, you are therefore “MAGA”/conservative. I’m not even American but if I was, I wouldn’t vote GOP either…
