The Tom Bower book on the Beckhams, covers a lot of detail about DB's alleged affairs, and the determination to keep Brand Beckham going.
He wrote about VB apparently leaning on Brooklyn for emotional support, and seems to think that he was party to a lot of details about his parents marriage that he probably shouldn't have known about. How true this is - who knows? AFAIK, no legal action followed from the Beckhams about the contents in the book.
The point about the name rights rings true, as Tom Bower also wrote about this as part of the Brand Beckham strategy - Brooklyn's name is a trademark owned by VB, it's visible on the Gov.uk register.
I imagine it would fuck anyone up to be a child in the middle of your parents' disintegrating marriage, which is being only held together for the PR and brand value, with journalists crawling about desperate to find the next crack in the facade.
I can absolutely see how he'd end up unhappy and anxious - throw into the mix that he's grown up in a blaze of publicity. Even worse when it comes to trying to find your niche, but you have no privacy to fail or get it wrong. His photos were terrible, but as he was 17-18ish at the time, I suspect the drive to publish the book was facilitated by his parents rather than him. If this was the case, then I think it's a huge disservice. Lots of teens try stuff and aren't very good; it's a normal part of working out what you want to do and hopefully finding something you like AND that you're good at.
