Is it really HN's place to attempt to influence the fate of Color? I'm not a fan of the app by any means, but I'm not sitting here hoping for it to fail.
Certainly that is not HN's place or purpose. HN's purpose is to provide high-quality Hacker News. Its readership gets to decide what that is.
(Sidenote: A side effect of that is, yes, a force that can influence the fate of one project or another.)
