I don't loathe Snap, but I do dislike their decision for not supporting Windows 10. Microsoft even offered a cash incentive to Snap for creating an app and Snap still outright said no. Surely no matter how much you hate a platform, if you're being offered an incentive, you would say yes?
There's a huge opportunity cost in putting some of your developers on creating an app for a niche market. Snap probably felt that Microsoft's incentive didn't cover that cost.
