Bitcoin is more free than the fiat banking system, but users are still subject to being censored, blackballed, and spied upon (especially at the interface between the crypto world and the fiat banking system).

If you want true anonymity, you have to use coins like Monero or Grin/Beam/Tari or shielded Zcash.
