they for sure lose money on some months for some customers, but I expect globally most of subscriptions (including mine that I recently cancelled) would be much better of to migrate to API
everyone that o know that have/had subscription didn't used it very extensively, and that is how it's still profitable in general
I suspect that it's the same for copilot, especially the business variant, while they definitely lose money on my account, believe that when looking on our whole company subscription I wouldn't be surprised that it's even 30% of what we pay
