Hard disagree. If you're running something business-critical, the support that you get with a RHEL license {or any other vendor, for that matter) is worth its weight in gold.
If you can't fix something, you don't want to be looking for solutions by sifting through forum posts directed at home users when the business is losing thousands of dollars per hour. That's what the license is for, and that's what you pay for.
Think about it practically. Microsoft is not an advertising company, they make their money from enterprise software. Windows is installed on billions of computers. The infrastructure required to accept and process every single key pressed by every single windows user and turn it into something usable would be enormous. And for what? To make a few extra millions by selling it to some advertising company?
