As the statement says I wont - it will be fully discontinued. This statement applies to the official app only. It doesn’t say anything about other apps or forks - any existing once can and hopefully will continue to exist. Also all the code is free.

I am not the creator, funnily that is/was one of the Lemmy creators: Nutomic :)
I am a syncthing co-maintainer that kept the android app on life support since a while.

It’s all in the open, you can go dig around for reasons. As usual there wasn’t a single simple one. Neither was it some kind of complete fallout, we e.g. collaborated on translations and I have been in contact around various things with the one that forked.

Oh don’t worry to much, mine too: If there wasn’t an alternative for syncthing on android, I might have kept it on lifesupport :)
