You actually think MM's don't support flippers? For pete's sake, they don't care WHAT any stock does. They facilitate the trades. Flippers trade more often than longs so MM's MAKE MORE MONEY on flippers. Every trade brings MM's money. EVERY SINGLE TRADE.
MM's don't have any interest to protect. All they need is buyers and sellers. They get their spread on every single trade.
MM's don't hold the price down or help it up.
If the share price is moving, it is because shareholders are buying and selling. Stock market 101.
MM's don't know ANY NEWS before anyone else - that would be illegal. That would make them technically insiders.
Where people dream up all these things to blame on MM's astounds me, because it shows such an ignorance of the way the whole stock market system works, and makes me wonder why ANYONE would put their money into a system they don't understand. That's like driving at full speed down a highway at night with the lights off. What you don't know CAN and WILL take your money away, eventually.
