I believe it is because their app was not updated in 2 years, and was auto delisted from Google Play. https://github.com/hidroh/materialistic/issues/1464

It is still up on F-Droid: https://f-droid.org/en/packages/io.github.hidroh.materialist...

Thanks! I didn't think about searching on fdroid.

Why does Google do this? Now I wonder what good apps I can't find due to them not being updated.

My guess is probably both to free space from their servers and to ensure that unknowing users aren't downloading an app that doesn't have somewhat recent security patches.
