You're not as strongly against ads as me, then ;)
I'd argue adverts are never ever truly useful as recommendation agents. They are inherantly driven by who has the money to run them. So they work against small, new, innovative players. Let's not forget, our contemporary problem is *not* that we have too little information about new, interesting things. Advertising serves to shift the balance of the things we hear most about to those of entrenched interests.
Then there's the whole not wanting to be manipulated by said interests any more than you can avoid (and people tend to underestimate the degree to which marketing works, even on them.) Or surveilled by them.
Any business model that relies on ads is one I disapprove of. It pushes the initial economic cost to the reader down to zero, but at too great a cost.
