For mega-corporations, "open" is just a marketing buzzword to beat their opponents with, so it isn't surprising that Adobe writes about "closed minds and open source".
For Google, open source is a neat technique to assert Android moral superiority over iOS (even though Google's core assets - search, ads - aren't open-source, and Android apps such as Google maps aren't open-source)
For Sun, it was a good stick to hit Microsoft with. Making software free and open-source was their way of competing with Microsoft and making money from their hardware business.
Adobe is now clearly in the anti-Apple/iPhone camp and needs to ingratiate itself with Android/Google. It looks like they're the latest company to discover the magic of the "open" buzzword. Sadly for them, I don't think it will be much effective
The problem is that the author does not cites the iPhone or Apple, and although he cites Android he hardly cites it in a positive way, he even provided two links that openly criticizes Android and it appears he is endorsing their positions.
Anyway, I agree with the big picture of your comment
