> Chrome can't really be sold. Right. Now try to use that top right "user" icon on your chrome window to log in as a user that is not from a google account.
No idea what icon you are speaking of. I don't use Chrome much and don't log into it when I do. I certainly don't think anyone is going to pay for the privilege.
Nobody is going to pay. But if google serve an ad for a logged out (or firefox) user, they get paid 0.05c if they serve the same ad to someone logged in (via that button or otherwise) they get paid 1.7usd.
the button is just to make you be always logged in.
You are paying all the time and don't even realize.
