Schwab, TDA, and others restricted trading on margin. A company saying "we won't loan you money to speculate on this volatile stock" is way different than saying "we won't let you trade this stock with your money", IMO.
I think so too, but as someone not in any sort of GME position, but on TDA (which is being acquired by Schwab anyway), this is a good reason for me to accelerate my search to move off the platform to a more retail friendly brokerage.
