I am far from knowing "my stuff" lol. More of a conspiracy-theorist guess.
MMs make money from volumes. They facilitate people buying and selling and take a cut on every transaction. They really couldn't care less which way SP is going, as they will make as much money on SP tanking, as they will on SP rocketing. The more volume traded per day, the better.
Volume goes hand-in-hand with volatility. The more volatile the SP, the more trades would be expected. If SP is flatlining, it's not making any money for the MMs.
It is therefore reasonable to assume that MMs love volumes and should be doing everything they can to promote volume. E.g. Be very open to lowering the ask to encourage buying or increasing the bid to encourage selling.
Now, suppose the MMS are not as ethical as FCA thinks they are. SP is stagnant because shares are in sticky hands but there is no significant buying pressure to move SP up.
A big order comes in and they need to fill it. Instead of the natural reaction to raise bid and encourage selling to fill the buy order, they significantly lower the bid to try and collect some cheap shares, yet they keep the ask the same, because they know there is no buying pressure at this level. It looks like SP is tanking (more people want to sell, nobody wants to buy) when the reality is that very few want to sell, and there is a big buy on the order book.
