Agreed. BigQuery, Cloud Spanner and Firebase are unique products which no other cloud provider can match even in the slightest. I think these things are a pull factor into GCP and everything else can be easily replaced once people decided to just move everything into GCP.
I got sucked into GCP because GKE is (still) much more advanced than EKS or AKS and that alone was a pull factor for me, let alone the other services which I mentioned.
