I've added the "since officially denied" remark to my previous post. We should give the Ethereum team credit for coming clear on this.
@Ursium: many of us understood Charles' statement in the introductory video(
https://www.youtube.com/watch?v=q5FDvzj8YX4 ) from 8:08-8:12 as if he were saying "work". The turned-on captions(cc button) under this Youtube video confirmed our assertion. This GS question hadn't just pop up from nowhere, his statement was interpreted this way. Anyway I'll take Charles's word for it....
The current list of devs is on the Ethereum website, you can contact them (or look them up) to see if they work at GS. What's with all the conspiratorial bugaboo?
