I don’t think the royal family thinks they have much of a choice at this point. There are plenty of people world-wide–particularly in the US–that see nothing wrong with all of H&M’s famewhoring. If they put a stop to the wedding, then they know that they would get more flack from the public about stopping the wedding. It’s only those royal watchers who pay close attention to detail and aren’t stanning Harry & Megs that think this shit show needs to be stopped.
