If they did that I'd immediately switch to something else. Nothing pisses me off more that spam. And all ads are spam. If I wanted something, I'd look for it. If you have to tell me about it first, then it's spam. Don't waste people's time/bandwidth/attention with things they didn't even want in the first place. And the counterpoint that "but they might not have known about x product in the first place" is useless. Because if they wanted/needed something like x they would have just googled "something that can do x" and found x.com or whatever to discover it. To reiterate, the fact that they weren't looking for it in the first place means that they didn't want it.
