Paid adverting artificiality maintains and promotes ideas backed by money rather than having ideas become widespread solely based on validity. If we believe in the "market place of ideas" where validity and accuracy are the sole determiners of success then none should have artificial support. So all ads should be banned. If an idea fails in this market place, then it is reasonable to assume it is a bad idea. Leveraging it is just as bad when done by Soviet approved posters or Exxon paid for ads. The echo chamber is an example where paid ads will actually _worsen_ the situation: Ads are aimed at target audiences driving them into more extremes by seeing exaggerated or false statement they would not have seen if there were no ads. Also, those echo chambers backed by moneyed interests will thrive and expand while those not money backed will fade. So instead of at least having some hope of uneasy balance between two extremes, you get head long plunge into just one of them.
