No. A centralized company does not want to create a decentralized cryptocurrency (coin or token), never.
USDT is created by a centralized company and the company try to diversify the chains they use from Bitcoin (OMNI layer) to ERC20, TRC20, EOS chains the USDT has still been a centralized stable coin. Tether can not deny the fact.
They could do it, but I won't believe they ever will.
Why bother if everyone uses it already at this point?
