They haven't cited any and likely can't. As an end user at the end of the day I care about real-world track record. Proton has not been able to comply to real-world requests over several years.

While theoretically there may be more secure approaches you may also be introducing new dangers as well. Eg; paying for a VPS with an anonymous coin doesn't mean your VPS provider can't deanonymize you or comply with a warrant. You need to make sure every single link in the chain is foolproof. That's way more error prone.

IMO a proven legal track record is in a way more valuable than unproven theoretical flaws (if you can even call them that).
