So now we have Bitcoin payment with actually just 1$ fee. To set up other competitive payment options would need another few hours not even days. And benefit would even lower fee. When the monthly payment is like 5$ you do not want pay extra 20% more to be cool. But definitely Ok to pay 48$ with 1$ fee. (2%).
And the way how to pay looks quite complicated for now. They generate for each account own address so than to collect all payment when Bitcoin fee will be bigger than now will cost a lot for ProtonMail.
So they does not have to set new payment opinion today, but definitely this year.
