I had 165M shares myself. But even though I do sell regularly, while the share price is increasing, I would never dump shares at market, which would only tank the stock. Others may be stupid enough to do that, but if they had that many shares, they would also be smart enough to know that they have to trickle them out to be able to maintain the share price, and even let it rise.
I still have 97M+11M++49M, for a total of 157M. But I've not affected share price ever - I only sell when the price is increasing, providing the shares that people want to buy. I will continue to do that, but only when the price is increasing. And, I would never sell a share at market. Everything is at a limit, which prevents share price decreasing. If the share price drops, my sells stop until the price recovers.
But you are right about one thing - it is not MM's shorting. It is all about buyers and sellers, and there are nearly 6 BILLION shares available to sell at a profit right now. SOME people will simply sell a bunch at market and move on. THAT is what affects share price.
