I think it’s the money that a lot of people are upset about. The taking of the advantages without the disadvantages of monarchy.
Nonetheless some people feel let down by H+M whilst others applaud them. My opinion is that they are cheapening the both themselves and the monarchy by their actions. To sell Harry to the highest bidder seems both undignified and tacky to me. After all, they already enjoyed a life of huge wealth and privilege before all of this. If they truly wanted to live a more quiet life away from public attention, then that was more than easily possible in the UK or Canada. Farming comes to mind, Princess Anne runs Gatcombe Park as a farm for example. Therefore I have to conclude that a quiet life away from the public is absolutely not what they wanted, what they wanted is extreme wealth for little work and to tread the celebrity path. And since Harry was very much admired as a royal, and incidentally never appeared to want to dump his life style before Meghan, it is my opinion that the person directly responsible for what has happened is Meghan.
I loathe this horrible and disgusting tacky behaviour from one of our royals. A quiet life was perfectly possible, but that is not what is happening.
