I have personal experience of a few companies in the UK where GCP are offering 90+% discounts to onboard. GCP are spending hundreds of millions to do this. K8S control-planes are a rounding error compared to this.
You could have grandfathered in current deployments but - nope. In the tech world this is up there with killing Google Reader.
There's no way I'm going to pay an extra $73/mo -- I already pay for the computing resources, this should be free.
Looks like I'll be moving away from GKE. It's a shame, I _was_ a big advocate.
