Exchanges are even bigger issues when it comes to centralized power and how they can freeze your account. Sure USDT can be very dangerous too and that's why I try to have none of it, but exchanges can literally block your account and make up some reason why you broke their rules and keep all your money. Then you can try to sue, but if you live in a different nation, that would be quite tough too, and would cause so much time lost and meanwhile they would profit from this.
Or simply any government could ask them to freeze your account and they will, just not to get in trouble with that government. So all in all, I can easily say they are not going to end up with any trouble, this is going to be a simple issue and I believe they are going to be dangerous in the future, keep your investments out of exchanges.
This is why we have a saying called "not your keys not your money" because if you are not putting your money in a wallet that you own, and not using a coin that is yours and decentralized, then you are going to have trouble. USDT is centralized, and Tether as a company has a right to do whatever they want with it, it is not something that is crypto and decentralized, it is a piece of digital numbers that they are giving you in exchange of saying that is how much you have with them.
Think of it like a bank, people who have a lot of money do not carry them on their wallet, they just put it in a bank, and bank shows on app how much they have digitally instead, and this is why I believe we are going to have something quite similar here as well.
