By its very nature, free software by definition allows users “to study how the program works, and change it so it does your computing as you wish”. Because of this, any restriction implemented in free software is basically ineffective, because people can modify the source code and remove those restrictions. We respect Tusky’s decision to block mentioned website; it’s their right to introduce restrictions like these into their software. We also respect Fedilab’s decision not to hardcode a login block; instead they are actively working on making it easier to block certain domains in the app itself and thus giving users more power to moderate which content they’ll see. If people disagree with F-Droid’s decision not to flag Fedilab, a idea is to develop a decentralized tag system based on package IDs which allow third-party servers to share their own warnings with their community.

Yep, can't argue with that, but why downvote?
