RH is in no way the next M$ (or at least in the way we think of M$). It seems to me that people think of Linux in the way that they think of underground bands. Way back when the Chilli Peppers hit the scene in the 80s, they were the coolest balls-out mother f*cking band around. Then when they started making money, selling out areans and becomeing popular outside the punk/ska scene--they magically became sell outs, even though their music always got better.
I think anytime RH starts to become successful and gets recognition outside the die hard Linux community, people start to think of them as being like M$. Just because RH is gaining decent vendor support does not mean they resorted to M$-like tactics to get it. I think people are migrating to linux because they finally have a clue on how computers should work for their company (I stress the word "work" here). I think vendors are moving towards it because its a quality product, not because they have $$$ to bully their way to the market space. I think people move to Red Hat because it has done a great job of making itself visible outside the Linux community.
All this article tells me is that RH has done a decent job at marketing their product, and their work has paid off.
