I didn't say those who don't pay for a service have no right to complain. I'm opposing the constant characterization of what Google and Facebook do [successfully and other companies do too but less successfully] which is collecting behavior signals to tailor ads and services is inherently nefarious. But again, if one opts to receive some service for free, they sure can complain but I don't think they are guaranteed any change to that service based on their complaint. IMO what matters is that users have alternatives and are not locked in.
