Do not attribute to stupidity actions that can be adequately explained by greed.

As some of the article’s comments say, the answer is probably the simplest: IBM.

IBM said they’d let Red Hat operate independently, but it was a matter of time before some of that corporate “culture” (aka stock-driven decisions) started showing through.

Hopefully the employees themselves aren’t slowly sinking into the IBM workload. I think a lot of them intentionally left IBM for Red Hat specifically because of the ideological difference.
