Re: in an ideal world.....
"adverts pay for most of the "free" stuff on the internet so if you use a service that is funded by adds, then let it be."
No. While I don't object to ads themselves, I strongly object to the spying that they bring and I am well within my rights to defend myself against it.
"If all these data slurps did was target relevant adverts there really would not be a problem."
In my view, that would not make the spying any less problematic at all.
