trade some of your data

This seems a wrong and misleading way of looking at it. Facebook has the data either way, and advertisers aren't getting the data either way. You aren't "trading" anything; the algorithms can either show you something relevant, or show you something irrelevant.

Personally, I'd rather see something I might find amusing. I was about to say "it hasn't happened yet", but I actually have clicked on one FB ad (ever) - the mysterious package company, which actually does look interesting. Not enough to give them my money but still, it's a start.
