Re: You brought this on yourselves
They may not get the same level of "analytics" they are used to but they get to know you saw the ad and if you clicked on it, which all they really need to know to get paid.
For which, frankly, the advertisers are probably better off. It enables the advertiser to put the advert on a page where it's relevant to the content. That context is almost certainly going to be more relevant to the viewer than any amount of "analytics" which are, of course, just something for which the advertising industry can con more money from the advertisers.
