Because who knows what it will be tomorrow?
We all knew exactly what CentOS was.
But goalposts are shifting, and none of us can be sure what tomorrow will bring.
I'm afraid my confidence in corporate tricks is extremely low. Just seen this sort of thing too many times before.
IBM did not buy RHEL for the shits & giggles. They bought it for profits. That is the driver.
A key point made on the list was something like "it'll be fine, but if streams don't work for you then just sign up for RHEL & support"
This is just a neat way to leverage you to a position. It isn't about what a stream is today, but what it might become tomorrow.
See the above quote from the CTO. I understand the original thinking on streams being more cutting edge. My guess is they'll become more so, despite promises.
But the problem then is they have removed the chance of staying on that stable base if you preferred it.
At least we have some time to watch the goings on.
