the middlemen aren't intercompatible. it's like saying anyone can make paypal.
If you try to start your own paypal, no vendors will sign up because you have no clients. No clients will sign up because you have no vendors.
My university forced everyone to use duo mobile for years, with no other option for OTP. That's what this reminds me of. Sure, there is a sense in which the university can choose to use a different 2fa service, but there is nothing forcing them and the consequences are on the user side.
