Because this is a complete troll piece to begin with, and adding Microsoft to the list just makes it blatant.
Then toss Microsoft into a list of "good guys".
MS aren't seriously listed as "good guys" they are only on the list because it was initially written in something of a "stream of consciousness" fashion, listing companies that jumped to mind, pro or con and then sometimes (as in the case of Microsoft and Facebook) immediately disqualifying them from the "good guys" list.
Nowhere is evidence given for Google "abdicating their position as such a champion," it's simply stated with the hope we accept it as a given.
Anybody who reads the news and is paying attention to what has been going on lately realizes that Google has changed. Are they completely "evil" now? No, but it's quite clear that openness is less important to them than in the past. They've all but declared war on RSS, they never implemented OpenSocial in Google+, G+ doesn't support any of a whole raft of standards that you'd use when building a social network if you cared about openness, Android has *never* really be developed in the open... it's "open source" but Google do everything and then throw code over the wall to the world. Now, don't look a gift horse in the mouth and all, and I'd rather have an Android code dump than no Android code at all. But the point is that there is a pattern present, where Google are showing less and less interest in Open Web principles.
Who owns Fogbeam Labs, anyway?
I do, along with my cofounders.
They claim to be "Open Source 2.0" (what does that even mean?)
We do? If so, that's a mistake, if you'll point out where you saw that, I'll fix it. You're right "Open Source 2.0" is a meaningless term. OTOH, we DO mention producing "Open Source Enterprise 2.0" products, where "Enterprise 2.0" is a widely used term (I happen to HATE it, but it's out there and we don't have much choice but to go with the flow on this one) that sort-of means something to people in the Enterprise space.
Yes, we're a startup. Most companies were at one time. :-) I however, as an individual, have been doing this stuff a long time. Go through my /. comment history if you don't believe me.
