I'm not saying closed-source is "bad guys" or anything like that. I'm just saying what I'm observing: open-source is picking up steam and maturing across the board. It's not slowing down at all. It's true that it will kill some developer jobs. But that can't be an argument for not supporting open-source (tech is always about getting more efficient, resource-wise, and therefor a job killer by definition).
Software in general is 'picking up steam and maturing a across the board'. We now have almost 2 billion consumers carrying a unix box in their pockets, not running open source.
If anything, the relevance of open source is dwindling by comparison.
