I purposely do not use the whole Proton suite for those reasons. It would be quite bad if one is entranched by their whole suite if they went on the enshittification route, which large companies eventually tend to do.
Sure the client is open source,
server code is closed source.
So if proton enshittifies or ceizes to exist,
the open source clients will be useless,
since you or someone else can’t host the server, since that is closed source.
But whatever man, good for you if you like them and want to remain oblivious of the risks! c:
2 words I want you to keep in mind:

Everything in Proton is
Then please do link me the source code of their email protocol.
FairEmail’s FAQ is the 1st thing that popped up on Github when searching for “proton”, mentioning that it’s proprietary:
https://github.com/M66B/FairEmail/blob/master/FAQ.md#faq129
…you mean SMTP?
No, I mean their email server + protocol.
The thing you’d use to self-host a proton mail email server.
What you linked is the source to the client,
which interacts with the proprietary server code to fetch your mail from them.
If you can’t self-host / switch to a different server if they enshittify due to being closed source, then it’s not “open source” nor “portable”
That’s…just wrong.
That’s not what open source means.
You can export everything and anything. And if you use your own domain you can take that with you as well.

You don’t need to host the server, you just move your domain to a different provider. It’s nothing more than a 3 minute DNS config change.
All the Proton software which you can install is open source. It makes sense to have some internal software not revealed.
