I think it's more of an assumption than anecdotal. Sublimetext is a very expensive piece of software. You have the forever trial thing, but people don't usually want to get hooked up.
And now piece of anecdotal - I don't know a single person around me that uses it.
Can't say I actually use Sublime anymore, although I do know a few people who do, but when put in the perspective of a piece of software you use all day every day it doesn't seem that expensive. Even when many other editors are free.
