The bigger problem is that Amazon has set themselves up as the global arbiter of commerce, acting as a relatively neutral marketplace matching buyers to sellers worldwide, replacing many or most of the smaller commerce hubs and marketplaces that used to exist.
But once in that position, they exercise control over which products can be sold with the explicit intention of destroying competitors, replacing what would otherwise be a consumer favorite with their own inferior (according to market preference) alternate.
Everyone talks about monopolists and moral hazard and market manipulation, but Amazon seems to be the only modern company with the unique combination of dominance, confidence, and poor executive judgment to actually make it a consistent and overt company policy.
