I think the heart of the problem is that Sony is a complex beast and there is no real control over who does what is which business unit.

This is recipe for corporate debacle in itself, and the bigger the company gets the more morally chalenged people try to climb the ladders, and the more a corporate culture of not screwing the consumer becomes important. A lack of unified values in the business units should in itself justify a "don't trust, avoid if alternatives are viable" attitude.

Now Sony headphones for ex. are really good quality, but you don't need to trust their privacy policies to use them.
