You are missing the point entirely. This is about vanity from the most privileged person in the country - vanity that we all have to pay for one way or another.
It is entirely pointless that we as a society have to pander to the current monarch's preferred fucking crown, especially when so many people are deciding between feeding themselves or turning the heating on (and other unenviable decisions)
Once again, you are very angry on behalf of people who probably disagree with you about this. I also have to question if you have actually if you've actually seen the change in question. It is the same design with one extra circle added, and the top bits shifted up a little. I could do that in about 5 minutes in photoshop. Tying this to Charles's choice also a bit of a stretch. He probably didn't think about the few places where the crown was shown on its own, since most of the re-branding involves his initials/face which he cannot change. You speak as if everyone in England is being personally subjected to his whims here, when really he made a relatively minor choice based on his tastes (and potentially not wanting to wear his dead mother's hat), which then caused some small changes to logos in other places. Heinz Ketchup is going to have to take the royal seal off the bottles because Charles doesn't like it as much as his mum did. Is this some kind of massive issue as well? Such decisions are made by random people all the time. Someone decided to subject you to a change in the colour of milk bottle caps which is much more impactful and I hardly think you are as angry about that.
