Any new owner is going to be a crap shoot, so there's no sense wringing our hands over one that's rumored to be in the market. The other thing is that Jody has to be willing to sell the team. From everything I've read, even though PA's trust says that both the Blazers and Hawks have to be sold at some point, I haven't seen a timeline on it.
Bezos was known at Amazon as having an autocratic management style, frequently overruling his subordinates. That's not necessarily a bad trait, and it's not clear whether or not he would continue that style as an NFL owner. Bezos knew his business at Amazon because he built it. He won't know professional football anywhere close to the same degree, so if he were to buy the team, I doubt that he'll be a meddlesome, Jerry Jones-style owner.
