The people doing the wrong should be the ones held responsible, at least at first. Saying that fake reviewers are not responsible for the problems they create is wrong. If you want to accuse Amazon of fraud-by-proxy that's one thing but even then by definition Amazon isn't the big problem to hold accountable.<p>And to their own point fake reviews are obviously not an impactful problem, if you want the free market to incentivize a solution then there's clear runway for the problem to worsen. Criminalizing ownership of a marketplace isn't going to shorten that runway it's just going to deny new entrants and further entrench Amazon and further isolate them from the free market, protecting this alleged malicious actor.
