Google doesn't care about you or whatever you're building, unless you are building something that might threaten them.

You would be well-advised to reciprocate. To the extent that third-party services are essential to your survival, making efforts to bring it in-house, get long-term contracts, have backup providers, etc. is simply prudent.

Dependency is control. If you build your business in someone else's sandbox, it shouldn't be a surprise that they can hurt you at their whim, and absolutely will do so if they can make a buck.
