You can now grab lemmur from f-droid and the Play store.
If you want to follow lemmur releases/news checkout the repo and/or follow the !lemmur@lemmy.ml community. You can always support the development on Patreon or BuyMeACoffee
PS. We do not flavor our releases: github release tab, fdroid, and play store apks are built from the same source code. Feel free to download lemmur from any place you like.
Well most apps work perfectly fine with the use of GPL3; lemmy for example uses AGPL3 which is the GPL3 license but adapted to the SAAS environment, even F-Droid uses GPL3.
I don’t see anything wrong with the GPL2 outside of the fact that is not compatible with the GPL3, if you’re concerned about dynamic linking and such I would advise the use of the LGPL3 which is compatible with the GPL3 license. But the GPL2 is fine.
