  Nice. This surely means they donated tens of millions to btrfs development.

  Darn. There is no discussion or elaboration on the specifics, just an offhand remark in an ongoing flamewar related to bcachefs :(

  I honestly don't think Btrfs is ever going to take off.

  We're better off just making a clean room implementation of ZFS, and just go with the better technical solution.

  Meta, although morally bankrupt, _usually_ makes sane technical decisions. Backing Btrfs isn't one of them unless they plan on rewriting the whole thing from the ground up, and from what I've seen in the linked presentation, they're trying to rehab the worst data loss and performance bugs. They will never find them all.
