Android Keyboards not being updated

Hoping the Foss community can help me explain why it seems keyboards like AnySoftKeyboard haven't been updated for years. Google play - Nov 2021 F-Droid - Jan 2022

The GitHub still seems quite active with changes being made 3 days ago. Is there a reason these aren't pushed to the standard distribution channels? I also looked at FlorisBoard and it seemed to show a similar pattern.

Are there any other FOSS keyboards people can recommend for Android?
