What 'open-source rhetoric'? It isn't a Valve Open-source blog, it's a Valve linux blog - open source is not really relevant at all to this post.
>After all, isn’t that what open source is all about – the idea that collaboration and teamwork achieve amazing things?
Yes, I suppose it is better for Linux if nobody attempts to sell commercial software which could work with Linux, ever.
This thread is a little overblown and it's too early to point fingers and thump chests - lets see what they put on offer first.
The word "damning" should not even arise. Don't lecture me about thumping chests and waiting to see what they put on offer, I am responding to inflamed language being applied to a company for no reason other than that they sell software.
I love what Valve is doing and I want to encourage them. Still, their usage is just a bit, 'missing the point'.
