I think that there was an element of disbelief from some who posted in response to the OP:
Was he bragging or boasting? Onw wonnders whether this is for real?
And an Apple site - or, rather, on a site discussing Apple, tech, tech related matters, and rumours concerning Apple products - and on a site where a great many posters (and members) admire (and, for some, it goes considerably farther than that), Apple and its products, naturally, there will fascination - doubting fascination, but fascination, when someone posts as the OP did.
Moreover, when someone from the admired company replies, or responds, - or reaches out and makes contact, with an individual, inevitably, this is a topic that will be of interest to many who are members of this community.
This is almost akin to a god - or the representative of a divinity - making contact with a mere human.
Thus, when someone - such as the OP - posts to make this known - about having been contacted by a representative of a company that produces devices and products that have become a core part of the sense of self, the sense of identity, of some (many?) who post on this site, and who are members of this site, there will be absorbed and fascinated interest, and, possibly, no small degree of envy, as well.
However, as some here have observed, Apple do, on occasion, seek to make contact with specific individuals.
