Hey, it's already a bit delicate to post about your company in someone else's launch thread, but I'd say it's over the line to do it in a putdown sort of way, so please don't. It's not in the spirit we're trying for here: https://news.ycombinator.com/newsguidelines.html.

(Just to be clear, although the OP is about a YC startup, for sure the same applies in anybody's launch thread.)
