" No matter what market, theres manipulation by the MM's."
This is categorically untrue
"BBIS currently top of the bid and the ask, setting their own spread without any other competition, in a normal market it would be frowned upon"
The vast majority of the dealing is done on RSP. What you see on the L2 is no more than a rough guide to the price.
In any case, if one MM is on both the bid and the offer it just shows that he is making a tighter spread than he is required to. That should be welcomed.
