It's an age old tinfoil hat theory of private investors, if you speak with a market maker, speak with colleagues in the city, speak with major investment companies, CEO's CFO's they will all say it's utter rubbish, mainly for the reasons you quote. There have been on occasion dodgy dealings, but having multiple market makers and tight governance it really just doesn't happen.
Notice no one moans about market makers when the price is flying. Guess why it's flying...because lots of people are demanding shares and willing to pay more than the current price....go figure.
