I honestly don't see what the fuss is. I thought the whole point of the Church of England existing was so the King could marry who the hell he felt like, and do what he wanted with them!
There's a conspiracy theory going round at the moment that the queen is already dead, she's made no public appearances for ages and all the filmed stuff is either old footage or deepfakes.
This is going to send them into overdrive as it will be seen as the soon to be announced king getting his priorities in as her wishes so he gets less trouble.
