There's ample evidence in the public record that John Wiley has an extraordinarily low bullshit tolerance. I don't think I've ever seen someone in such a politically connected position with such an obvious allergy to other people's crap. It was perhaps inevitable, then, that the agenda of Wisconsin Manufacturers and Commerce ("We want a highly skilled workforce and first-rate infrastructure and *NO* we don't want to pay for any of it.") would tend to rub him the wrong way, especially as the university budget is chronically hamstrung by the horrible political culture they dominate.
Wisconsin's prima donna business lobby took the full brunt of one of Wiley's rhetorical stiff-arms today and I don't think anyone is surprised that they immediately started bawling.
I'll admit, I'm too lazy to check it out myself but it appears WMC's list of "factual errors" contains a few . . . well, factual errors. The Journal Sentinel pointed out that, if WMC actually did lobby for the passage of the university budget, they failed to report it to the state. Illusory Tenant piled on by helpfully explaining to James Buchen that, really, ad hominem is a fancy Latin word for a personal attack so, yes, WMC most certainly did level personal attacks against Lewis Butler.
Another high-profile shot across (if not into) WMC's bow. On the one hand, you could say that all of the heat they've been taking has been coming from "Liberal Madison." On the other hand, you could say that they've now been castigated by the state's most successful high-tech firm (Epic Systems) and the leader of its largest economic engine (UW - Madison). For a business lobby, things could look better.
