factual: Amazon does this factual thing X and this factual thing Y, and it shouldn't be happening this way.
First one is just an opinion piece, regardless of its truthfulness, because it cannot be evaluated objectively (how to objectively determine whether amazon cares or not? who counts as "amazon" in this scenario? what factual event led to this statement? and on and on).
Second one is a factual statement that can be evaluated on a true/false basis. Events X and Y either happened or they didn't. If they did, the responsibility for those can be traced and evaluated. It leads to actual results, while the former is just an emotional opinion sort of statement, but that's exactly what sells the headlines.
