I do think it's distasteful, he didn't need to donate proceeds from his book, I'm sure he has millions of his own that he could give if he was so inclined, but this way, his book is promoted and bought by well meaning people who want to help who have a lot less money to donate in the first place, he is doing nothing but riding a wave of publicity.
He could have simply done a post on social media saying he had donated £X and encourage others to do the same, started something viral like the no makeup selfie or waterbucket challenge, he has the reach and influence to do so.
But no, instead he promotes his shit photography book and makes sure his grief tourism is photographed and published for all to see. And the photos are patently shit, certainly not worthy of publication or exhibiting. Most 16 year olds who get into photography can do better, I certainly took much better photos as a teen on a camera much lower in quality than he will have as did many of my peers, he makes no comment on the type of lenses he used, or displays any knowledge of technical details or an ability to explain why he chose to include the shots he did. I'm sure he has the best equipment possible at his disposal but seemingly can't take a decent picture? He should be embarrassed not proud. Yes his life would have always been like this due to his parents and enormous privilege, but piggybacking on the Grenfel tragedy while living moments away in his mansion and promoting his book off the back of hundreds of deaths of poor and vulnerable people is abhorrent. He and his parents should be ashamed of themselves.
