I remember Google starting to charge for managed Kubernetes clusters a year or two ago, I think the cost went from 0 to 75$ per month.
Maps API's I think went up pretty big time on google side.
There were even several posts on HN around that time period of personal projects (maybe even companies) going under because of the price change.

That plus shutdowns of things - google is not most stable
