That's a strong claim.  And it is basically as false as it is strong. 

There is a lot of discussion about BTRFS regarding performance and stability. And because BTRFS is so superb fast and reliable, Red Hat has dropped BTRFS in RHEL. They don’t want something so fast and reliable in their distro. This would probably make the (paid) support redundant and reduce the profit. And customers could become overwhelmed and dissatisfied with so much speed. </irony>

BTRFS has a number of advantages, but also some disadvantages. A slightly more accurate and less operationally blind presentation would be much more appropriate. As is almost always the case with Technology, it's a matter of balance and differing relevancies.
