The value of proton is not that they'll break the law for you -- they absolutely will not. They are bound by the laws of the land, and when compelled will hand over all the data they are required.

The value IS that they simply don't have that much data. All your emails are encrypted at rest with a key they can't read. All your data is stored in such a way that they can't decrypt it on demand.

Think about it. When Microsoft gets served a FISMA warrant, everything they have is stored in plaintext, so they have to hand it all over. With Proton, all they have is your IP, the date you created your account, the last login date, potentially the subject lines of any messages in their mail queue, and that's about it.

Nobody is going to risk their business to help people hide from law enforcement, and anybody that says they will is probably lying to you.
