OISE a scam?

I applied to MT mid April and I heard back last week saying I got waitlisted. Based on this thread it seems like majority of the people hearing back now are getting waitlisted. It's clear that they don't have anymore spots to fill and there's already a long list of people waiting, so why are applications STILL open? I want to give OISE benefit of the doubt but I can't help but think that they're just keeping it open to earn more application fees. Has anyone gotten accepted recently?
