It's fair to allege all kinds of externalities and privacy impacts and such around the advertiser-driven content economy. And HN is 100% here for that.
But this is stepping across the line into a simple lie. They don't sell data.
As a deliberately hyperbolic example: "We're not selling child slaves, we only offer a marketplace where clients can bid for the use of the labor of our child slaves."
The problem is the intrusive violation of privacy involved in building giant databases of personal information on every person on earth, not that someone-other-than-Google is doing it.
Then have that argument, please. If your argument is that "privacy impacts of advertising are bad and here's why Google's business model doesn't improve that" then that is one thing. Telling people that Google is selling your data is a lie.
Yet here you are with the "WELL AKSHUALLY..." brigade.
