I wonder.. I don't think that applies to everyone.
Most of the stuff I buy is either commodity (clothes, always the same t-shirts, pants, shoes, my colleagues joke it's my 'uniform'), food, or weird-ass stuff that nobody advertises for. Like second hand computers or electronic components to build cool stuff.
And reviews I usually get in depth from other users on tech forums like XDA and local ones. Before I buy a phone I know pretty much every little thing there is to know about it :) Not just the gloss, all the annoying bugs too.
The only thing I buy that's really advertising sensitive is games I think. Or some hacker/maker stuff you'd see on hackaday. I know advertising affects me. But I'm pretty certain not a lot of my purchasing is driven by advertising.
