Do you have an alternative hypothesis for why advertising would be inversely correlated with satisfaction?
If not, it seems like we should operate on our best hypothesis with evidence for it, not speculate about unknown unknowns.
You did at one point say that advertising might not be causing the lower satisfaction, it might just be exacerbating other problems that cause lower satisfaction. While that possibility certainly warrants investigation to see what those other problems are, it doesn't have any implications for how we treat advertising: either way we should be seeking to decrease its influence on our lives.
