Yes, and I have the same opinion about Redhat.

No issue with their actual paid service levels; it costs them to run those, and they're providing value. Most corporations won't use software unless they have a telephone number to call when it breaks, and service level guarantees. That's worth paying for; it's a service. But the fact that they're charging for software that includes some that I wrote, and which RHEL got for free, and for which I receive no kickbacks, is inexcusable.
