First, I would point to a couple of sources that picked up on this precise point in meeting the arguments of Stoics and others in the years after Epicurus:
What is Happiness? Let's let Diogenes of Oinoanda explain:
What is the true end? Let's let Torquatus make the point very clear in "On Ends":

Ok - here is a link to Hiram's post:
I am attaching a full pdf of the article, but there is one clip I want to be sure to emphasize, because I think the writer cited is absolutely correct:
We can of course cite the many instances in Epicurus' own texts, and in Lucretrius, which precisely point to "pleasure" as the goal and guide of life, but I will add those here later.
You will also want to reread the arguments on this topic in Elayne's - On Pain, Pleasure, and Happiness Second Draft
This Epicureanfriends forum is no doubt the "some Epicurean circles" being referenced, so here is a thread to discuss it.
