Here's my abridged summary AFAIK:
Hiring Manager: *job pitch*
OP: I'm doing fine and don't really need this but go ahead then, let's see this.
HM: *more info*
OP: [detailed critical breakdown of the pitch including accusing the company of a bait and switch]
HM: LOL ok buddy, snark snark
OP: Never talk to me again
HM: *accidentally or intentionally sends internal recruitment feedback to OP*
OP: Stop harassing me
HM: Sorry wasn't intended for you, snark snark
OP: Stop harassing me!!!!!
And that's it.
Yea, to me at least this seems like a non issue, and as if the OP is one of those people who is muddying the waters around what actually constitutes as harassment.
I mean Christ, a couple of emails? Just ignore them and move on. If the guy was continuously emailing over and over, I might understand, but 3 emails when you yourself are also being condescending and blunt? Come on.
Also, in future all you have to do is politely decline a job, not get in to it and give it a holier than thou.
