When the business model is the privacy violation
One argument he raised in the House hearing was that collecting data on users allowed more targeted ads which in turn made ads more efficient and therefore more economical, which levels the playing field more for small businesses versus large ones in terms of advertising.However, that is an argument favoring the customer, i.e., the advertiser, not the product, i.e., the user.During the Senate hearing, he was asked about Ms. Sandberg's comment that if there were no ads then users would have to pay.  Mr. Zuckerberg pointed out that users can opt-out of ad targeting/data collection,[1] making the ads they receive more generic and less "relevant", but currently Facebook offers no option for users to pay not to receive any ads at all.The still unasked question is, "Why not?"If some users could not afford to pay, as Mr. Zuckerberg suggested in both hearings, then they could opt-in to advertising.  How would this affect the business model?Further, if those users were disappointed at how the ads they were being shown were not "relevant", then they could opt-in to ad targeting/data collection.1. The default setting is opt-in.  As we know, most users do not change default settings.
