Being run by the project developers left after the primary dev’s departure and (if you’ll excuse the drama) betrayal by selling to what amounts to an advertising company. Personally I’ve started supporting this project on github, as losing these tools would be a massive blow to the open source Android ecosystem.
Are these available on f-droid already?
No, but it’s coming. Near as I can tell Gallery is the only one with a new release already and I’m grabbing it using Obtainium.
