There's no maybe about it: Snapchat definitely doesn't want them. Evan Spiegel has been very upfront that he doesn't want the riff-raff. Snapchat has always been deliberately shitty on Android and Spiegel went out of his way to make clear how they definitely weren't going to make a Windows Phone application, back when WP was a potential player. If you're not a cool, hip teen with an iPhone, you can piss off.
He reminds me a lot of that Abercrombie CEO who said that they didn't want fatties and uglies in their stores, which was a winning strategy until it suddenly wasn't.
This is partially why, as much as I hate Facebook, I'm not particularly upset at Snapchat slowly getting steamrolled by them. Businesses that stick up their middle finger at potential customers out of snobbery deserve to fail.
