We have a TAM, but it doesn't buy us much. They use their TAMs as a sales lever to get you to use all of the vendor-lock in features. They'll help you architect your platform so that it won't run anywhere else and charge you for the privilege. You can keep telling them all you want about how you operate multi-cloud and how you won't budge on that and they'll just keep trying to run higher up your flag pole.

For actual issues needing real support, like when anything breaks, they're useless.
