I felt like this about Google services for a long time now. However, we decided to go with GCE for some of our recent / less critical work and to be honest, I've been really happy.
We had decent support and even our requests through non official channels like slack communities or direct emails got responded / followed up. Services seem as stable as AWS. And most of the tooling is better.
I think they are doing a great work recently on Google Cloud. Granted, we built everything with "moving to AWS should be easy / possible in case Google fucks something up really bad" in mind, which proves your point. But locking in does not scare me more than it does about locking in to AWS at this stage.
Based on your slack channel comment, I assume you're using Kubernetes. That's a great choice for new development, and I'm glad you've had your questions answered! I can't tell though, did you also use one of our paid support tiers? (https://cloud.google.com/support).
