This looks as ugly for WireGuard than for F-Droid.
WireGuard current app on Izzy repo for F-Droid does not tell users where it's updating from, does not ask for consent and it's opt-out. So there were clearly not happy about letting users know.
Not to diss WireGuard which is course an awesome project.
A growing number of Izzy repo apps are reproducible builds.
