Re: The default should be no slurp whatsoever
That this argument is nonsense is indicated by all the websites that continue to use paywalls.
Also, you're presenting a false dichotomy. Ignoring the fact that there are ways of generating revenue that don't require data slurping or paywalls, there's nothing to stop sites from offering users a choice -- pay and don't be subject to spying, or use it for free and be spied on.
I'm not aware of any sites that actually offer this choice, though.
