The other thing is that a bunch of stuff it auto-completes is way below any reasonable threshold for a copyrightable work even it bit for bit reproduces code from a piece of AGPL software. There are also only a finite sane number of ways to implement basic data structures like single- and double-linked lists in common per language. If I lay claim to the copyright for all of them should that prohibit anyone else from implementing the data structure (without unreasonable contortions)?
