You are assuming that GrubHub has anticipated every possible accusation against them and has intentionally crafted their response with respect to each and every one.
That's silly. No one has the ability to do that. GrubHub was responding to a very specific article which made a very specific claim that GrubHub was squatting these domains in order to lock restaurants into their platform. The most relevant response to that claim is to point out that they will transfer the domains if requested. The article in question did not make your "financial blackmail" claim, and there's no reason to expect that GrubHub would have anticipated it.
