I'm sure that's what he was talking about, if he wasn't being sarcastic. But there's a difference between releasing a bit of code on the periphery of your walled garden and being a "role model".
I would never ask a for-profit company to open source their core software if it doesn't meet their business model (sell support, etc.). Here's the thing though: I don't care one bit about how they process tweets internally.
However, the "bit of code on the periphery" that Twitter has released is far more interesting to me. Bootstrap lets me prototype web UIs much faster, for example, and who knows? Maybe some day I'll end up using their contributions to MySQL, Cassandra or Mahout.
So, if only for purely selfish reasons, I say kudos to them.
Kudos for the good things they've done, sure. And criticism for the bad things they've done. But "OSS's best role model"? Laughable. That was the post I replied to.
