No, all my Gmails and Outlooks still work. It's only Protonmail that stopped. Support didn't reply.
All of that said, if it says nothing else it at least suggests that larger providers seem to have a better grasp of how catastrophic being locked out of one's own e-mail can be - PM really don't seem to understand the responsibility they bear being a provider of such critical infrastructure. If this were happening in this same way at larger providers like Google and Microsoft, I'm quite certain there would be heavy regulations by now.
