Frozen token accounts before and after the revoke
A freeze authority is the address on a Solana mint that can freeze any account holding the token, a buyer's included. A frozen account cannot transfer its tokens, so the holder cannot sell or move them until the same authority thaws it. After a revoke, no wallet can freeze any account of the token or thaw one that is already frozen.
Any account frozen at the moment you revoke therefore stays frozen permanently, because a thaw also needs the freeze authority.
Regulated stablecoins keep a freeze authority on purpose; USDC's belongs to Circle, its issuer. For a token not created yet, the Solana token creator can remove freeze authority in its creation transaction. That is part of its 0.15 SOL fee.
