Personally I didn’t think the pregnancy test one really counted, either, but I’m with you on this one. This isn’t just “I put Doom on a sex toy,” but “I put Doom on a sex toy and used game events to trigger its functionality,” which is a level above.
Also looking at the pregnancy test one now I might change my mind. They did use a different microcontroller and screen, but the pregnancy test already had a microcontroller inside it; it just wasn’t programmable. If the replacement microcontroller and screen had the same specs as the old one, it’s more than fair to call that a win IMO. At that point, it’s the same hardware, after all.
