Maybe for sites which require registration (and hence explicitly accepting terms) that could be argued, but there's certainly no implicit agreement to download and process all the stuff the site is offering to the browser.
And "entitled" is just a lazy insult.
I don't mind if a website owner gets that stats for himself. What I (and a growing number of people) mind is that huge corporations collect that stats and then track me down and crunch the data to show me "personalised ads" (of products I already bought) and categorise as a person of interest group XY and then selling that data including my email address to evil spammer YZ.
It is quite the sense of entitlement to think you have a right to that information. You have a right to log what people ask you (the server logs); logging anything more just makes you a creepy peeping-tom.
> I don't mind
That's nice. That doesn't mean everybody else agrees.
You're right, in general - it is the aggregation at Google (et al) that is the real problem. My point is that it is highly presumptuous to assume everybody is ok with a particular type of logging.
