It is not the same thing. SyncThing's model of having to add every host to every other host (possibly with introducer nodes) is much more complex. With Bittorrent/Resilio Sync, you can just give someone else a read-only or read-write key for a folder, and they become part of the swarm. Also, Resilio Sync supports encrypted-only nodes, which participate in the swarm by providing bandwidth, but only see ciphertext. This makes it possible to use e.g. an untrusted VPS as an always-available node. Unfortunately, Resilio had to ruin it with complex enterprice-y license schemes.
