Well, to be fair, Facebook was the company that created the always open "floating bubble" concept, to my knowledge.
Link Bubble behaves very similarly to Facebook Messenger in this way (the way the bubbles move, how you interact with them, close them, etc), and I can't help but think that Facebook was inspiration for the project.
This is actually a good thing because I always thought that the Chat Heads were a novel idea, though Link Bubble's implementation of the concept is rougher around the edges than Facebook (e.g. "laggier", not quite as clean in design).
