If it was e2e anonymous services, I would agree completely, however their policy indicates it's different. They apparently selectively choose who and what to host. It's not even clear it's encrypted.
I'm not arguing that they are guilty or bad, but rather that this is different from a bad actor using Proton over For.
A/I merely selects and filters the individuals to whom the Services are delivered to in order to reduce the risk of violations of our policies. By preventively asking to submit a written statement of intents, we can evaluate the affinity of every Service request from potential new users before any account is approved; the aforementioned statements are always evaluated in person by an appointee of A/I and deleted right after the request process is terminated.
Every written statement always undertakes a non-automated process of case-by-case examination, occasionally involving some follow-up questions and observations that the appointee will send to the requestor in dialogue via a dedicated webpage.
