This is a good move!

In my opinion, any platform should be available for free for any non-commercial purpose. This is how people get started, and this is how the platform proliferates.

I might even suggest going a bit further: provide some limited support for non-commercial users, for example, make it super-easy to file a bug.

But otherwise, it's a win-win for both the free tier (students, hobbyists) and the corporate.
