As far as I know this is the case for many pegged currencies - especially ones run by companies in the US. I know the Paxos pegged tokens can freeze accounts and I wouldn't be surprised if it were the same for USDC and others. They just build the level of control they want into the smart contract (which is often required to get various regulatory approvals in the US).
It is a good reminder that just because something runs on a decentralized blockchain doesn't mean someone doesn't have control over it. If you're concerned about that sort of thing, then DAI is probably your best bet for a dollar pegged crypto, but it has its own set of risks.
