I am still angry for them for their blackmail-based payment model back in years. For those who don't know, you were able to get credits for Proton from Humble Bundle. You are able to use those credits to use "Pro" plan. Well, once your credits ended, without any notification, your credits started to go negative. After certain point of negativity, your account was locked for "unpaid" bills. There was no any information that this would happen. You weren't able to access you email unless you paid the bill.
