There is no „inclusion of LVM technology“ in BTRFS. LVM provides you with several separate filesystems, completely independent from each other. A file system failure in one LVM volume does not affect any of the other volumes. All data in other volumes are safe. In BTRFS, everything is a single huge file system, (sub)volumes are just logical groupings within a single, in the worst case faulty, file system. The advantage of BTRFS is greater flexibility and effectiveness of disk capacity usage, at the expense of data protection.

BTRFS protects us from "silent" corruption of files, which is more of an issue with large volumes of data.  The greater flexibility and effectiveness of BTRFS minimizes the need to reorganize filesystems when a partition runs out of space.  For large organizations with many users, btrfs is expected to reduce problems with data corruption, time spent paying users to do housekeeping tasks, and the added wear on flash memory of reorganizing filesystems.
