I’ve noticed the same thing, and I think it’s for a couple of reasons:

As noted in another comment NBC is an absolutely terrible steward of the broadcasts in the US, but they spent the money to help prop up their football investment.

The second is that the IOC is driven by greed, and dictatorships have money while craving any legitimacy they can get on the world stage. It’s been shown in multiple studies (sorry I don’t have time to look them up offhand) that only a few cities have managed to pivot the Olympics required investment into a profit by any measure (including public good, which is where I recall the few that are considered successes hinge their measurements, i.e. LA). That drives the actual Olympics into those countries arms.
