I understand the scenario you are describing. Basically it assumes that exchanges will take the whole market hostage.
This is very similar to the theoretical idea that in bitcoin the big mining pools will take the mining hostage and only build on top of each others blocks and censor small miners.
In your scenario the big pos stakers would take the staking hostage and not validate what small validators (=non exchanges) do.
I have no solution to this game theory thought. But in the bitcoin scenario everyone of the big mines would have an incentive to ally with small miners to have an advantage over other big miners. Idk if that help and an equivalent could be found for your eeth game.

Correct, mining could theoretically become a shitshow. And it would only take a conspiracy of a few pools to have 90% hashing power.
But don't forget that pools consist of individual miners that would sanction this kind of centralization because it is in their own self interest.

This is more related to the proactive vs reactive security, IMO. Since performing this attack on Bitcoin would require much more than 51% of the hashrate to pull off, plus the direct cost of maintaining the attack.

More realistically it would immediately create a fork in PoS since I think they're more fragile to network partitions.

Agreed. Pow incentivizes time/energy spent on the thing that one already did spent time/energy on (which is also why there will never be a 1:1 copy of bitcoin). Pos does not have this natural self incentive. In any ethereum fork people can just stake on both forks which is detrimental with ethereums centralized foundation and a demi-god vitalik.
