It's not that it's closed, it's more that none of the exiting email protocols support a server which can't read your email (as it's all encrypted). They do offer Proton Bridge which you can run locally which will handle all the decryption and local mail clients can talk to that as the would any other mail server.
I don't know off hand if it supports calendar syncing though.
I'd say the main benefit Futo has over Heliboard is that it has native swype typing with its own model (and also own voice typing model).
Still a bit light on customisation (certainly compared to Heliboard), but a nice first release certainly.
Proton is not the same as a VM. It has direct access to your filesystem. It could delete your entire home directory if it wanted to.
Another vote for Immich. It's a really nice experience on both the web and app.
Ah, so it isn't just me. I had noticed this myself recently.
Even if it doesn't look as good, it'll hopefully include some better APIs that extensions can utilise to improve their experience. E.g. hide the native tabs.
As I understand it (from my non-legal casual read of the new coverage). Having a monopoly isn't illegal, abusing it is. For Google they found that google was secretly paying companies to not put their apps on other stores. That was what they got the judgement against them. They didn't find anything like that for Apple.
I believe Steve has said that he hates the title/thumbnails too. But Google's algorithms heavily incentives them, so he reluctantly uses them while maintaining the good quality content.
Droid-ify can auto update apps in the background with root. I'm running it on GrapheneOS without root and it's doing it just fine.
It's been a while since I've had to touch it too. But couldn't Alice provide Charlie with both the plain text and her public key. Charlie could then encrypt the text and see it came out the same as blob Bob sent Alice?
Typically end to end encryption includes digital signing of the message so you can verify who the sender was.
You can get notifications in other profiles. However it'll be a generic "Profile X has a notification". Tapping it will swap profles, but not exactly seamless.
