Indeed, in Oakhurst, there was a genuinely ambiguous construction, caused by a series of gerunds, a phrase composed of a gerund, preposition, noun, 'or', noun. You could read it two ways.
Here, if you try to separate "engage in the business of" from the list of gerunds that follows, or pretend that it only refers to designing, you'd still need to explain what all those other gerunds are doing in the sentence.
It's clear, as Derek has pointed out, that they have been doing 6 of the 8, and doomed is their weak -ass attempt to use the precedent Websters v. My Third-Grade Report to explain that to promoting a competing product to their customers is not competing.
But here's the fun: their MtD does two things: one overtly, and one half-hidden. Overtly, they claim that Skadden doesn't mention in their analysis "engage in the business of", because those words would make their case weaker. It doesn't, of course. We had this discussion already. "In the business of" excludes incidental cases, such as if CIG were to point out a vulnerability in Unity.
The sneaky part is that they change the GLA's "which compete" to "that compete" and imply that the SAC reads it as "which compete". I don't think the SAC reads it this way, but the MtD doesn't want to spell out the literal reading of the passage:
"which compete" is plural. That means that it refers to a plural subject; "any game or middleware" is singular, and, if you wanted to refer to it, you'd probably want to use the restrictive pronoun ' that'. So the subject of "compete" is the list of eight activities, and ' which ' should be non -restrictive, meaning that 2.4 forbids CIG from designing, developing etc. any engjne or middleware, since those activities compete with CryEngine.
That's absurd. Skadden/CryTek aren't claiming that. FKKS/CIG are saying that they are, and, the funny part is that the contract actually says what FKKS/CIG falsely claim CryTek says it does. This makes Oakhurst a walk in the park.
De minimis. 'which compete' was meant to refer to 'game engine or middleware', and it doesn't make a bit of difference: however you cut it, CiG loses.
