F-droid is as centralized as Google Play. It's just have different overlords for the app catalog. Obtainium is the only real way to download the app from source.
Yes. I got an app merged into F-Droid and then they banned it.
Did they give you a reason as to why?
One of the F-Droid moderators made an account on the website and used search to find a specific post of someone saying "I hate trans people" and then used that post as a reason to delete the entire app.
Yeah, that is rly messed up.
Github is owned by Microsoft. Assuming that most of the apks come from there using Obtainium then there's not much difference
There is... It's one less overlord.
Developers should abandon Github and use a more decentralized kind of platform, or use mirrors with Github (like some GNU/Linux distros do with their packages), otherwise Obtainium will be only a band-aid solution
There is a difference. Microsoft doesn't dictate requirements for software made available through github in the way that Google and F-Droid do for packages distributed through their channels.
"From time to time, GitHub receives requests from governments to remove content that has been declared unlawful in their local jurisdiction. Although we may not always agree with those laws, we may need to block content if we receive a complete request from a government official so that our users in that jurisdiction may continue to have access to GitHub to collaborate and build software." https://docs.github.com/en/site-policy/other-site-policies/github-government-takedown-policy
Github is evil
That's pretty much what you'll find with every US organization that abides by the law. But there are many other git alternatives available if you find GitHub's ToS unacceptably restrictive. The main benefit to using GitHub is its 3rd party integrations, and the accompanying functionality.
