Not just for students, but also OSS developers (who Github said they would give Copilot for free). I know this because I am an open-source developer, and over the weekend my Copilot was degraded to the point that it's virtually useless. (It was pretty annoying because I was doing Ludum Dare this weekend, and making extensive use of Copilot until it suddenly stopped working.)

The dumbest part about this whole thing is I would happily pay $10/month for Copilot if given the option. However, GitHub won't even let me switch to a paid plan! The setting in the admin panel simply says that it's already paid for and won't allow me to switch.
