I have had a Tuta (Tutanota) account for years and they’ve always been good (I just have a free account and it’s always been fine for my needs) https://tuta.com/

While in theory it is nice that an organisation would give over so much power to its customers in terms of where donations go, it does come with the risk of problematic decisions being made. Then later, when they’ve boxed themselves into a corner, quite unnecessarily, all they can do is go along with what their customers decide and then pass on the morality of that decision to those customers. But that’s not really good enough to say “My customers made me do it!” No, you gave your customers too much power in the first place. It’s a privacy organisation so surely better to give some money to a group that supports and compliments your aims. Bellingcat (regardless of the problems raised in the article I posted) has nothing to with privacy. If people read the article and decide they are happy with Proton, then go for it. I’d rather people make a decision with their eyes open.
