I'm still not convinced that's a bad thing. Does this not ensure profitable sites will be around because they provide enough value to their users to charge a fee, everything else will be stuff like passion projects.
I really just feel that 1. Advertising is manipulative and evil in its' modern form, and 2. Targeting further multiplies its' ability to do evil.
I'm not convinced that what we receive in exchange for empowering 1 and 2 is in any way worth it.
