Could Circle freeze USDC on any wallet address just like Tether did to USDT?

Recently Tether froze 160m USDT on Ethereum. This makes me questioning about the censorship risk of stable tokens issued by centralized entities.

USDC by Circle, BUSD/USDP by Paxos, WBTC by BitGo, etc. Do these tokens can be freezed by the issuers?

How about partially-usdc-backed stablecoins issued by DAOs like DAI by MakerDAO and FRAX by FraxDAO? What will happen if Circle freezes USDC held by those DAOs?

Which stabletoken is truly decentralized? Algorithmic stablecoin on other chain like UST by Terra and cUSD by Celo may have unreliable collateral. sUSD by Synthetix is also collateralized by SNX which may has similar reliability to Terra and Celo.

So, does the truly decentralized stablecoin must only use ETH as collateral? If that's so, then so far as I know, the choice is RAI by Reflexer and LUSD by Liquity. RAI is unpegged while LUSD is pegged to USD. I might just pick both 50/50 as my stable holdings, but RAI is issued by Reflexer Labs which is based in the US, is that a risk?

To be clear, I'm not trying to shill any token/protocol here. I want to find a stablecoin which is the most decentralized stablecoin available rn bc currently I hold tens percent of multiple stablecoins. Can't imagine if those funds are frozen
