Actually this shows how knowledgeable you are on network cards and how business works. If people want a cluster, you sell of course with the cheapest components you got, if they are happy with it. Yes this is why myri is pushed, because 99% of all academics don't even know there is other networks faster than myri for hardly any extra price. As the routing system for big clusters is same price. Actually ask some IBM salesman here. He'll tell you that he will sell a cluster regardless of which network the customer want, just default they use myri.
