I use Ubuntu, the free, open source, off-the-shelf release, and I am not forced to pay for a "Red Hat" version to rely upon it.
You *could* pay for Ubuntu, if you wanted, though.
The question being raised is this: Is Drupal being driven to be such a fast moving target that real time-to-market costs can only be afforded by large shops?
If the answer were yes, then we are forced to examine whether economic/financial/corporate interests are at work pushing it in that direction.
Canonical is credited with speeding up the development of Debian, quite the opposite of making it "business friendly" by slowing it down. If we're going to compare Drupal (and Acquia's Carbon) to Ubuntu, the more accurate comparison might be Drupal=Debian, Carbon=Ubuntu.
Instead of sweeping the issue under the carpet.
