ProtonMail iOS app goes open source
The apple store always distribute apps under a proprietary license. So even if the code is open-source, if you install it on your device through the apple store you are still installing proprietary software.They say on their Github page that their app is licensed under GPLv3. Yet they can't publish it under GPLv3 license to the apple store. This means that if you contribute to the project under the GPLv3 license, they can't redistribute your through the apple store. So if you contribute your code it will always have to be licensed under a permissive license.Still can't wait for the F-Droid release though.
