If anybody is worried about their identity leaks, data leaks, etc. and are thinking on how to save themselves from these issues, I bet they'd go for anonymity first. That's because keeping your data online or in the hands of these untrustworthy companies makes you vulnerable towards the fact that these companies will just use it to be sold to other companies for some USD (even cents). Now, if you believe that your information and data should remain transparent and you don't need anything to hide from anyone, then you may also choose not to go anonymous but that's something I'd never prefer to do.
