There is a way to do it, you just don't want to figure it out. You want to FORCE them to figure it out for you. BooHoo.
Again, this is a commercial product, that they open sourced. Their commitment was to release the source. They then additionally went thru the step of providing free services ( free binaries, open support system, etc ). This has not worked out for them, they also need to run as a business. They are still giving you ALL of the source.
RedHat went thru a similar period, and in all honesty, was the only thing that saved them as a company.
If a Centos projects comes out of this, awesome. if XCP ( Xen Cloud Platform ) comes back as a volunteer project, awesome too!
"Opensource" is about many things. But to me, and many others, one of the early core tenements has been that the users of a product help out in some way. It doesn't mean you get to whine your way into others doing free work for you.
