here is how to pause updates of Syncthing-Fork from F-Droid until the situation becomes clearer
based on code reviews done by people in the Syncthing forum, any version up to the one currently available on F-Droid is probably fine. however, nobody really knows the person in control of the repo, so you probably want to disable updates for now.
to do that:
1. open the Syncthing-Fork listing in F-Droid
2. open the menu in the upper right
3. make sure "ignore all updates" is checked
