Basically title. I waited on installing F droid for a long time because my phone threw many scary warnings when I tried a long time ago. But now I have it, and I got some fossify apps, but since there is no “Editor’s Picks” on F- droid I dont really know where to go from here.
What apps do you recommend I install first to remove my dependence on closed ecosystems?
What is my vulnerability surface ie, which sort of apps should I watch out for?
Are there any bad faith companies in the open source sphere?
Beside concrete suggestions, I would suggest having a look at the applications you use. (Decide whether you actually use and need them first.) Search for the application on AlternativeTo or similar sites and look for a FLOSS alternative there. And also search the internet for general FLOSS replacements for the use-cases of the applications you use. No need to rush anything. Even replacing one application a week is good progress.
