I'm not happy that Alex was working with this 'creep' Terry Richardson but it's his job. I don't justify him for that but also I don't condemn him.
In normal life there are similar situations all the time, you don't always work with those whom you like or respect, sometimes you just doing your job (best and fastest you can) with some people who arouse disgust in you, but that's life. Fashion word is a strange place. Sometimes it seems to me that those who are more fuc*ed up are more popular, noticed, appreciated, they never go away for good.
In the last few years TR shot some very prominent faces as Viggo Mortensen, Charlize Theron, Adam Driver, Clint Eastwood, Justin Theroux (who is also TR friend) and many more. He has even taken Barack ***** and Oprah Winfrey photos and comments and relations about his disgusting behavior have been known for many years. Here interesting article about TR and some stars who still are on his instagram with smiles on their faces and thumbs up
