The price hike was insane yes, but because they were eating the price difference. How exaclty does moving to a Claude sub is better, when it's actually more expensive ?

At my company we did the comparison and Copilot still wins: for 20$ you get a seat and 20$ of usage, whereas with Claude enterprise you get a seat and then usage is completely added. Moreover usage in Copilot is exactly the price of the providers AND it allows us to use various models from multiple providers.

The case that might be less expensive is if you negociate a volume discount with AWS for Bedrock usage, but that is also possible with GitHub and Microsoft.
