I doubt the validity of the OP's statement, though to be fair, unless you've access to the source, there's no way of being sure what data might be being reported back to manufacturers.
There's certainly a lot of spyware around: I spend most of day my cleaning it off machines-but much of it is self-inflicted (not necessarily intentionally) by installing every little bit of trialware under the sun, not reading the small print (and missing the half-a-dozen other items which will be installed alongside whatever free utility you've downloaded), or looking for access to sports/movies from non-legit sources.
