On the one hand, sure. Facebook's brand is about as hip as a bag of Werther's Originals.
On the other hand, this is one of those things (like VR) that is a distinctly non-Facebook project. It makes no sense to position or market this as "Facebook" research. The Homepod isn't called the iPod Home for obvious reasons, so it stands to reason that Facebook execs realized selling someone a "Facebook Quest" sounds like a metaphor for ayahuasca. It's not entirely stupid to rebrand, especially considering how diverse (and undeniably advanced) they've become in fields like AI and VR.
