Yes, it looks awful --- but is far from the worst looking building around .... look at most of the monstrosities that went up in the 60's and 70's.
But ..... (personal feelings towards Charles apart) ....it was an abuse of a priviledged position.
I disagree entirely .. he had an opinion .. so he aired it. just like you and I can and do. The fact the developers listened and acted on his opinion is not his call.
Are we saying that he cannot have an opinion, or voice that opinion
In the subsequent totalitarian state.. who would decide who's opinions are allowed and who's are not 
Freedom of speech applies to everyone.. not just those whos's views you agree with.
Yes, he is entitled to have an opinion, as are we all. However, it is not true to claim that we have complete freedom of speech. Our actions are still (rightly or wrongly) controlled by State, Tradition, Constitution, Law, Political Correctness etc., etc.
In this case HRH ran roughshod over the planning process by running to his powerful friends in powerful places. Could he have not, as per the planning process, merely have written in with his objection, as Mr Windsor, to the correct planning authorities?
As it happens, I (reluctantly) agree with Charles's opinion on this occassion, but not with the way he acted. An opinion I am also entitled to hold
