distrust is your perversion, because, without Market Makers there would be no guarantee of a "BID for every potential seller" and an "OFFER for every potential buyer". They provide liquidity and depth of the market for price investigation by large or block buyers and sellers.

Yes, they can act as Principal in any transaction(s)namely trading for their own account, but it is governed by rules as set forth by the exchanges.

Let the joy of having Market Makers in ELVA, be something we all can be thankful for, tomorrow and beyond.
