I'm long gone and never signed anything so have no problem mentioning that we were quoted USD$150/m per vCPU core with a 12-month commitment (from memory).
The project called for a minimum of 4 replicas and likely 8 vCPUs per, so right off the bat that's close to $60k/year before you even do anything. Plus the unwelcome addition of "license anxiety" to the whole development experience, and being forced to make a big decision up front.. it's not how I like to work or what a startup needs.
