It seems like Jerboa uses GPLv3 as well, as does Bitwarden and some other open source apps. Its probably ok though it seems like it can run into trouble way down the line. Im going to keep the GPLv3 for now.
It seems that the lemmy-js-client
library you are using is licensed under AGPLv3. So I’m not sure if you are allowed to use it with your current license. You might have to make your project AGPLv3 too.
The Apache License 2.0 is compatible with the GPLv3 and AGPLv3 but not the GPLv2: https://www.gnu.org/licenses/license-list.html#apache2. Using an AGPLv3-licensed library in an Apache 2.0-licensed program is allowed, but you must follow the AGPLv3 when conveying it, which is incompatible with the Apple app store ToS.
AGPL is a Copyleft license, so how can it be possible to use such library in an Apache licensed program? Isn’t the whole idea of Copyleft to make that impossible? To make sure that nobody can take away users freedoms?
I think what they meant on gnu.org is that you can use Apache licensed code in a GPL licensed program.
