BTC is freedom, but it depends on how you use it, if you store your BTC in a centralized exchange or custodial service, then it is no different from using fiat, if you lend your BTC out, to receive interest in return, you have no freedom. Not your keys, not your coins, the only correct way to use BTC is when you have your coins in your open source, self custodial wallet, only then can no third party confiscate your funds.
