@res260 I don't think so. They want ads that work - but ads without tracking have been used already for well, at least a hundred years. We know they can work.
I'm not saying that backpedaling what has already been given away is an easy task.
I believe it is still worth pondering over.
@bagder if you take TV or newspapers for examples of ads that worked without tracking, these are two examples of services where ads were not the only source of revenue. An online news site, it pretty much is these days, except donations, or its behind paywall :/
