Well, at least say WHY? We know we can't trust Apple (because of the recent backdoor that had to be closed down), Facebook because of the Cambridge Analytica scandal, Microsoft because the NSA were given first access to vulnerabilities before patching), the NSA because of the CLOUD Act), etc as these are all documented, analysed and reported on. Your comment really adds zero value to the debate. Proton is under Swiss law for a start, which has a way higher barrier to entry for law enhancement to get any access to metadata. In the USA the law enforcement just buys that data from data brokers. Proton is not in the business of advertising.
