At any point in the process, does it warn you about setting up recovery with personal email addresses?
Feels like with as much as Proton advertises nowadays as a privacy protecting service, they need to be taking into consideration that a lot of their customers now are going to be average users who don't know anything about proper OpSec. They should be much clearer about what things they can't protect you from.
It shouldn't be in a press release like this, they should be explaining the difference between privacy and anonymity to the customer. It's not like their marketing team isn't aware of the fact most people don't know any better.
It's in their best interests, too, because it doesn't matter how many times you say "we provide privacy not anonymity", the headlines are a bad look.
