The point is to try to lump Google together with companies that literally do sell customer data, e.g., credit card providers, supermarkets, stores at the mall, magazine publishers... They literally sell your non-anonymized, non-aggregated data, period.
It's an unfair lumping because what Google does is a far cry from that.
I didn't read it that way at all. I can see how it can be read that way, but it can likewise simply be read as making it clear that Google cares about advertisers rather than users.
Whether or not a subjective interpretation is that she is "trying to lump" Google together with these companies, she did not come straight out and make such an allegation in the article. When you then imply in your comment that she did, it's a bit rich to accuse her of "unfair lumping" afterwards.
One way of capitalizing on that, without selling the data, is to sell access to advertise on the basis of that data.
The point is not to claim that Google is selling our data, but just another way of stating that we're the product, not the customer.
