They definitely lost revenue. People use RHEL/CentOS because a load of software only officially supports Enterprise Linux. But why would they pay for RHEL if CentOS works fine?
By taking out the CentOS Foundation, which was NEVER going to sell support. They created 2 companies that will sell support, and they still have the same issue.
At the WORST those companies will have to buy a RHEL license somewhere in here, if Red Hat takes away redistribution rights on the srpms... they might as well put a gun to their own head.
SuSE will take the business gladly.
Which software is that?
But the people who are running Db2 probably has very little overlap with the people running CentOS, too.
