Thanks!
Can you make the images clickable? They’re impossible to read at that size.
I will look into it, there might be a zola option for it. If there is, sure!
This paragraph should probably mention that this won’t work if the provider uses E2EE
That paragraph is in the context of what I call "transparent encryption", which means E2EE works until the provider is not compromised and the E2EE is effectively broken by delivering malicious software or disclosing the key. E2EE is as resilient as the security of the provider, which is why picking a trusted one is important. Of course, compromising the provider and breaking the E2EE is quite complex.
Not that I know, which is the reason why I essentially didn't consider those threats relevant for my personal threat model. However, it's also possible it happened and it was never discovered. The point is that there are risks associated with having the same provider having access to both the emails (and the operations around them) and the keys/crypto operations.
If I were a Snowden-level person, I would probably consider that though, as it's possible that the US government would try to coerce -say- Proton in serving bad JS code to user X. For most people I argue these are theoretical attacks that do not pose concrete risk.
