as indicated in my separate mail, we should differentiate between
1 - privacy-preserving personalisation by 3rd parties (i.e., data re-use 
across sessions within a 3rd party context)
2 - information transfer from 1st to 3rd party context
3 - information transfer from 3rd to 1st party context

My subjective interpretation is that Walter et. al. discuss (2) and 
maybe (3) while David seems to raise a point on (1).
