This happened to me with Google in 2002. Back in the heyday of the desktop widget craze, Google approached me several times via email wanting to discuss acquisition of my widget application. Bear in mind, this was when Google was just buying stuff up wholesale, rather than absorbing the team behind an acquired product. I eventually responded, and the rep and I set up a phone call - solely to discuss the sale of my code to them. I was pretty surprised when the person I spoke to jumped into a full-blown tech screen. I humored it initially, and was then subjected to meeting-reschedule-pinball. Super weird bait and switch by the googs.
