There’s actually a video of it too that a lot of people haven’t seen (Video visuals are SFW, though there is gunfire sounds in the distance in the second half). The image alone misses a lot of what the guy did, he even climbed on top of the tank.

Droid-ify is an F-droid frontend, that is also in F-droids repo as an installable app so it’s safe, in this case one of the F-droid repos OP has is actually malicious and is installing a modified version of Signal, the package name is wrong org.thoughtcrimes.securesms, it should be thoughtcrime without the S.
I think Play Protect is intrusive, but this time it actually tried to protect OP from a malicious Signal clone.
