You are. Let's take what you said "... aren't running a tech company."

Nothing in the article said he's running the company, you are making an assumption here.

Nothing you have provided at all backups up your claim that "It's often not a good sign when the top engineers or star salesmen aren't running a tech company. ". So there's an unproven statement combined again with the assumption that engineers aren't running the place (the article says it's being run by one of the co-founders, who was an engineer - "Prior to founding GitHub he worked as an engineer at CNET Networks on Gamespot and the launch of Chow.")

"You say he does "corpdev" and the article clearly points out "development of the corporation" has become a big problem. "

This badly misunderstands what corpdev does.

It's pretty much not worth continuing this discussion, i'm just pointing out that you are making wildly silly generalizations to how to run companies and what the article actually says. And yeah, you are making a ton of assumptions to do it.
