The case for credible neutrality: USDC could be bought for <0.9$ over the weekend, but CEXs stopped trading to not let you make that trade

Another reason why we're on this journey on the vision of crypto. Coinbase and other CEXs stopped trading of USDC for customers over the weekend. But people with their own keys and own wallets could happily buy USDC for less than 0.9$ for a limited time during the weekend on DEXs.

Aside from the fact, that this is very unfair, that CEXs can simply stop users from making such trades in such "emergency situations", do we need any more reasons, why we want our money out of CEXs?

What do you think?

Could we use this example as a reason to the many ppl who own Crypto, but only have that on their bank/CEXs and thus were actually limited in their power due to their "trust in these institutions"?
