"Red Hat was, and is, leaving a lot of money on the table."
But is it? Consider some of the possible scanarios for different customers if the clones closed down.
1. RHEL user for both production and test, training etc - let's call these non-production uses ancillary - no additional money made.
2. RHEL user for production, clone for ancillaries but would be able to afford to convert the latter to RHEL licences - money on table here.
3. RHEL user for production, clone for ancillaries but converting latter to full licences would not be financially affordable , will manage to struggle along with late version clone/CENTOS-stream or some other distro - no additional money to be made.
4. As 3 but decides to use another distro for future projects - no short term gain, likely long term loss as current production purpose reaches EoL.
5. As 4 but decides to actively migrate existing production usage so as not to split work between two distros - complete medium to long term loss
6. As 5 but reluctantly needs to buy extra licence for ancillaries during migration - short term gain followed by loss in medium rather than longer term.
7. Running entirely on clones, could afford to buy licences - money left on table.
8. Running entirely on clones, licences would be unaffordable - no money left on table irrespective of what course of action they take.
9. Not currently RHEL users but were considering it until now - loss of future sales prospects
Those in scenarios 3 - 6 currently using some S/W or H/W product currently RHEL users are likely to be speaking to the vendors of those products in the near future if they aren't already and said vendors likely to be considering their positions already.
So in some scenarios there will have been money left on the table which they could pick up. In others there's no prospect of that happening and in others there's money to be lost in the longer term, especially as 3s slip into 4 or 5.
Whether this is a real money earner in the long term depends on the balance between the scenarios.
My guess would be that there are bonuses to be made in the next quarter or so as the immediate gains are made after which it will be time for the execs to emulate the rest of their customers and move on.
