Honestly, yeah, I think so, but I wouldn't describe it as a cult. Much of the Morey praise is more humorous than real. I think he's a great GM, but I think Les is the real mastermind for having the guts to hire him, and giving him the resources to do his job.
Well, 'cults' does not only refer to religious cults. You have movies or TV shows which have developed a cult following, i.e. loyal fans.
'I already plan on dying, Morey came to me in a dream and told me to kill some folks so I'll join him in heaven.
Pritchard's cult following in Portland is much bigger. Mainly because Portland basketball fans are much better than us(sad to say). And I assume Presti's following in OKC, another BBall-only town, would also be more than Morey's.
