Because every time btrfs is mentioned, 5 more people come out of the woodwork saying that it irreparably lost all their data. Sorry but there's just too many stories for it to be mere coincidences.
Your statement is misleading. No one is using btrfs on servers. Debian and Ubuntu use ext4 by default. RHEL removed support for btrfs long ago, and it's not coming back:
> Red Hat will not be moving Btrfs to a fully supported feature. It was fully removed in Red Hat Enterprise Linux 8.
