1. You are the user in question that is a co-founder for PIA.
2. You are a direct competitor to Proton*
3. "Messengers", especially in the position of founder of the competitor, have significant bias.
4. You have a fiduciary reason for them to fail.
5. user protonmail has noted significant harassment regarding this issue
Im inclined to distrust both of you. I find that your arguments might have merit. But I also see you as a digital aggressor. I don't particularly like either.
