The key issue is that malfeasance is ignored.
When fledgling companies enter the market seeking funding for growth, they are targeted, and soon, the likely d3ath spiral into bankruptcy follows.
The moment it became acceptable to tolerate unsettled trades and refuse transparency in favour of regulatory conflict of interest or data protection, certain entities saw this as a chequered flag to manipulate as much as they please. In addition to numerous others, DJT and TSLA have both been vocal in objecting to stock manipulation.
The worse they can expect if regulators actually regulate is a mickey-mouse fine that is a fraction of the money they have stolen.

It's innovation and investors that pay the ultimate price. 
Innovation is suffocated, as in the case of MMAT, amongst many others. Investors lose access to funds when companies attempt to leave public trading to go private, as in the case of MMTLP who have been brutalised by a two-year refusal to provide any firm of transparency or support from SEC, Finra, US government and international regulators such as @TheFCA. Otherwise, investors see their funds disappear as the stock is shorted into the ground and forced to dilute for survival.

Don't be surprised that they've finally had enough.
