Unless you are naive enough to assume that ProtonMail is incapable of logging IP addresses (in which case they'd be incapable of serving HTTP requests...see the problem?) then they can log. And they most certainly aren't going to declare independence from Switzerland and refuse to turn on IP logging when required to by law.
Whereas with E2E-E, they actually are incapable of turning over readable emails.
what other status quo do you expect from them?
Having to provide IP logs after a warrant has been issued is the law in switserland (and most if not all of the EU).
Sure, the law would (hopefully) be changed, but at the moment, this is the best they can legally do?
I, for one, will not renew my ProtonMail account if that's their status quo.
