Circle buys Poloniex - Gov-backed market takeover?

Circle, part owned by Goldman Sachs, purchased Poloniex for $400 million. There are rumours circulating that the SEC told Circle they would waive prior regulatory infractions.

The poster of that information proposes at the end this could be good for crypto. Is this necessarily true? Does this not constitute government aid/support/approval for a state-approved established financier to take over a blossoming anarcho-libertarian free market? How many other exchanges will we see bought up by big banks?

I'm starting to wonder will crypto markets really be the disruptive force to big banking monopolies that proponents, like myself even, loved to proclaim.
