What about companies like Epic Games that have few repos but many users? With their 2 private UnrealEngine and UnrealTournament repos they would have been paying $25 a month and under the new pricing structure will have to pay $815,913 per month... edit: That's based on what I can see as a UE4 subscriber, 2 private repos and 90657 users.
We are reaching out to customers that are in unique situations such as the one you're mentioning here. If you have questions about how the pricing changes affect you, please don’t hesitate to contact support@github.com.
Gotcha.
