After reading the issue you linked I came away very strongly in favor of continuing to use F-Droid. Why would I want to switch to an alternative distributor whose policies would permit the WireGuard devs "I don't want to provide a clear explanation to end users" antics? (Of course I happen to trust the WireGuard maintainer, but individual cases should generally be irrelevant when setting policy.)

I am impressed to see the F-Droid maintainers sticking to their principles.
