fraud and/or trademark infringement.

i only play a laywer on HN but seems categorically different than the safe harbor dmca which protects youtube etc since google has full control?

same for the amazon case. amazon for fraud and/or tm infringement.

the buyer of the ads as well in both cases but of course those are smaller pockets to empty.

it needs to be done legally but i will say that ads can benefit startups and small companies wrt building awareness against brands which already have it - so i dont think 'ads are the scourge of the earth' but of course rule of law needs to apply.
