Correct me if I’m wrong, but, regarding the first point, in what way are the calendar clients proprietary? Unless I am missing something, the clients for iOS and Android are open source and licensed under GPLv3 while the desktop client (part of the mail app) appears to be licensed under AGPL v3.
The email system not working with Thunderbird etc. out-of-the-box is true but that is kind of understandable, considering that the emails are only stored and transmitted to the first-party clients in an encrypted form that other clients couldn’t work with? And you could use the mail bridge (which is also open source, if I am not mistaken) to expose them as a local server to be used by Thunderbird etc., right? Maybe not ideal but I’d agrue it’s “fine”.
I do agree that there are things to dislike about Proton but those two don’t seem like problems in my opinion…
