I’ve been following this on X/Twitter and I think one of the most egregious things that’s important to point out is that folks from Phrack reached out to Proton in private multiple times, and Proton ghosted them. Proton only engaged with them and then reinstated the accounts after Phrack went public and their X/Twitter post went viral.
It also looks like one of the writers filed an appeal with Proton and Proton denied the appeal, so they manually investigated the incident and refused to reinstate the account and then only did after this got attention on X/Twitter.
