Yeah I think most people confuse privacy with criminal behaviour. Proton has your back when it comes to the former, but they aren’t there to enable you to pirate or cause trouble, hiding behind their service.
I don’t see how making sure criminals are brought to justice is the same as protecting your anonymity on the net.
And even if mandated under law, it’s not like they actually log your travels and are handing that to law enforcement. Whatever they hand over still falls under their services guidelines.
