The “Caveats” section for BTRFS is trash, it is all about a ENOSPC issue that requires you to low level mess with the thing or run the fs for years over constant writes without any kind maintenance (with automatic defragmentation explicitly disabled). Frankly I can point from the top of my head real issues they aren’t speaking about: RAID56 (everything?), RAID10 (improve reading performance with more parallelization).
If we take subvolumes, snapshots, deduplication, CoW, checksums and compression in consideration then there’s no reason to ever use ext4 as it is just… archaic. Synology is pushing for BRTFS at home and business so they must have analytics backing that as well.
