So you hate them and they deserve to be name called because they do things in the public? I think you are misunderstanding what they mean by privacy. They don't want paparazzi to follow them around, climbing fences in hopes of getting some "scandalous" picture of them. I really don't think that you understand what was actually happening to them. How are they "lashing out" at their families? Meghan has been trying to defend herself against her nasty family. I actually feel really bad for her dealing with that crap.
I am sure if she hadnt treated her father so badly, he would never had posted those pictures and everything that came after it. When you hear about Meghan's past relationships and friendships, she comes across as someone who dumps people when they can no longer benefit her.
Meghan behaved like a new hip manager who came into a very traditional company, where she decided to do things her way. If she had slowed down and first did things their way, she could have later added her way and be brilliant at her new job. It is a job for life, and saying after 18 months (which is awfully short on a lifetime) that it is not for you, that comes across very bad. People loved her when she arrived and her fairytale wedding, there was plenty of merchandise. And people loved to see her.
It is how they handle things that rub people the wrong way, not what they say. Nobody can hear what they say, because how they say it is much more interesting. I always find it funny that Meghan hates Trump while in how they handle the media, they are very alike.
Combine that with that everything they do is aimed at an American audience, not British. Meghan not pursuing getting the British nationality (if it was that important to her, she would make effort to get it during the pandemic) keeping her lawyer team in the US, etc. She comes across that she has dumped the British public, now that they cannot serve her anymore.
And indeed that they cannot keep their mouth shut when they have to and do stay quiet when they need to talk. Take that last sentence in their own statement, that was uncalled for. That gives off vibes 'we know/are better than you'. It was a cold response. The Queen wants them to be part of the family, but they dont seem to want to be hers.
I think the Queen only lets them keep their titles, because otherwise she would have lost them forever. This is a way to keep a connection. Or because they need their titles now to keep the American public interested. If she takes those away, she would harm their future.
Unless they do get political.
