I want to throw out though that every fascist and totalitarian movement in the 20th century also had nothing but the best of intentions and was guided by truly moral people who genuinely had the best interests of the people in mind. So saying someone is a good person with well-intentions doesn't mean nothing, it's actually a huge red flag.
Also this is obviously a third party interception of private communications between two parties without consent. It's wiretapping. Wiretapping laws need to be extended to cover textual representations of conversational discourse.
