There's no need for SEC to redefine market manipulation - IMHO the "pumping" activity of at least some WSB activists would perfectly match the existing legal definition of market manipulation as written to prevent historical "boiler room" type activities.
On the other hand, in these discussions I have seen a bunch of assertions that what the shorting hedge funds or HFTs are doing is "market manipulation" - now that is an attempt to redefine market manipulation to something entirely different than what it is/was.
