GrapheneOS Sure, he is a scammer and things have to be said in a way that people get the message. Yet preferrably in a polite way.
(I meant it in a more broader and a social way.) The reaction of people like him when being critisized will be more false accusations and hostility... it will go down a rabbit hole fighting each other on who said what and did this or that first. (That's a pattern I recognized which must not be true, just my perception)
I think you did quite well achieve a professional tone. As a strategy you could have targeted privacy & security scammers in general and make him and others an example of it. So then it's you vs a problem and not people. I think you get the point.
Thanks for your great work and...
