Link, or it didn’t happen. LOL
As a developer, Google offers a lot more tools …
+1 AntennaPod user from f-droid, on a device with Android 7. (Aside regarding AP) A couple strange/inconsistent things I noticed - In settings, app permissions, AntennaPod wants Location and Storage. Why location? Oddly, both are disabled, but it works OK anyway. On Google play web page it lists those permissions and more. On AntennaPod privacy web page it only lists Storage and View WiFi connections.
As a user, your comments on not having numbers for non-play store users are very interesting. Most privacy statements are so long and vague I interpret them as “anything can happen.” Yours is (thank you!) more brief than usual, and mostly says we don’t track you, but has enough “excepts” to give some uncertainty as to whether some data is sent home or not. It’s good to hear some apps don’t call home.
This might be an option to consider?
You also falsify my assumption app developers benefited more from f-droid users, because they were more likely to test new versions, file detailed bug reports, and help debug issues (but unfortunately AP beta versions from play store lead, and f-droid versions lag). I’ll be sending you a bill for my therapy costs. AP adds to my “fear of missing out” because I can’t keep up with all the subscribed podcasts. (half joke)
(Back on topic) Annual or monthly memberships seem to work for FSF, and annoying popup campaigns seem to work for wikipedia as you said. You might try adding a “buy f-droid a coffee” at the top of app lists in the f-droid app, and move the “buy the developer a coffee” to the top of app detail displays (instead of buried lower down). Yeah, add “donate now” or “join now” images to every web page, charge by the byte for downloads, split the proceeds with the RFP submitters, make this forum “members only” and see what happens.
