Acacia/IP Innovation has gone on the record as saying that it's not trying to kill open source: it just wants to suck anyone and everyone dry of cash, regardless of license. I don't know about you, but I feel strangely comforted. :-)
IP Innovation is not attempting to inject itself in the ongoing philosophical debate of whether products or services which utilize open source are subject to the same intellectual property laws/behaviors as non-open source offerings. Acacia and its subsidiaries do not philosophically differentiate any company, but rather seek to consistently and fairly monetize patent rights from those companies which incorporate patented technology.
So there you have it. Acacia is just a troll. We can rest easier now.
