There are plenty of open source operating systems available. Therefore it's not a good idea for Proton to waste time writing another one.
ProtonMail is perpetuating the problem by using Google Play Services (GPS) for notifications. I've degoogled my phone by installing LineageOS without any gapps but ProtonMail requires GPS to push notifications.
I'm going to switch to Tutanota until Proton fix this reliance on Google Services.
