If you deposit BTC to a centralised exchange they display your balance but they don’t necessarily have to keep that BTC. They may have users that have a total balance of 1 million BTC but only hold 500 K BTC in their wallets due to hacks or other bad decisions they have made. If you had the BTC in your wallet with your own keys the balance will show what you have with no risk of deceit.
I see this crackdown on Trumpism more as a response from the state because it was threatened than a response from the left. There may be many on the left who cheer this on, but it is not directed by those on the far left. This is a response from the state. The state does not care about your right of free speech if there is an attack on it. The state will protect it’s power structures no matter what.
