Tether froze $25M USDT of crypto exchange

Russia‘s largest and sanctioned cryptocurrency exchange Garantex has temporarily shut down all of its services after Tether froze over 2.5 billion rubles worth of USDT. So it seems that crypto is not as decentralized and unregulated as one can think, and they would still voluntarily obey the governmental regulations, although they don't have to. Since as we see now even the top world governments can make 180 turns on politics very easily, this is especially worrying. I wonder what long-term consequences it can have, considering a serious blow to the trust to Tether.
