Re: I have but one question
Depends what the wording is.
In this context a better word is "trade", because if they are trading information about customers with 3rd parties, without consent, for financial gain -
Well that is technically a commercial relationship.
It sounds like a good development. Marketing droids remain the worst offenders on stuff like this. A desire to "gain audience insights" and a typical lack of IT knowledge, combined with a complete disinterest in customer privacy is never a good mix. It is literally not in their career interests to have customers requesting privacy.
