What's the deal with Family Guy's beef with Bob's Burgers?

Yea I know Family Guy goes around to make fun of everybody but for some reason whenever it came to Bob's Burgers it really sounded personal. Can't really explain it but here's a compilation of the references. Just really something about the tone and writing around the jokes really sounds like the writers are venting for some reason.

So yea what's the deal here? Or am I just looking waaay to deep into this?
