Interesting take on it all, but really, I think you are grinding a personal axe. And a little behind the times, as well as not totally up to speed on why some things happen the way they do. In fact, I would say you are spectacularly biased, and not totally well informed.
Maybe you would be better holidaying in Skegness. Forget world heritage. If the World Heritage badge isn't worh a candle, then Dresden will still be Dresden without it.

I also think you need to distinguish between UNESCO's actions and the actions of the World Heritage Committee, which is independent of the organisation's bureaucrats such as Banderin, who really has no come back to the committee's decisions
As for 'anti-development', it depends on the development, and the particular circumstances of that development, surely? No two places are alike, and, for example, in Bath no-one is objecting to the Western Riverside being developed, but they are objecting to the plans which have been passed which they don't feel are good enough for the city. It was the same with the Dyson Academy; no-one objected to its re-use, but they did object to its butchery, and the unsympatheic design of what was to replace it. There was a call-in, but Dyson withdrew the plans, so the affect on the WHS was not tested at inquiry.
(Re logos, they are not supposed to allowed to be used for any commercial purpose. Seems fair to me.)
