No one holding GME is having their holdings seized.
No one holding GME is prevented from selling (by Robinhood; periodic circuit breakers do inject halts for everyone during periods of high volatility/price movement, which are rules set in place before [this] play began)
No one is prevented from opening an account at the many dozen other brokerages who are happy to transact in GME.
Your take is so wrong. There is friction in opening accounts, funding it, etc. If all your investment money is in RH, it takes a week to move money out.
And the simple fact that millions of people on RH are locked out of buying totally fucks the people holding the stock. "You can sell but not buy"?
RH is a business and can make their own decisions. If you are not happy with how they service you as a client, you can take them to court. They do not owe you anything more than what's in the contract you have with them.
What about people that already lost money because of this movement? On the other side, on the sell side there might be lots of people who were holding waiting for a higher price that was driven down by the blocking of new purchases, cratering their gains. Is that right by the rules of the game?
