A lot of it is because platforms need a wedge against AWS/Azure.

Take edge computing for example – most apps are CRUD apps that talk to a single database, but vendors keep pushing for running things on edge servers talking to databases with eventual consistency because hey, at least AWS doesn't offer that! (or it would cost you 10k/month to run that on AWS)

For the problem of eventual consistency, Google's Spanner and Firestore both provide strong or tunable global consistency. Instead of "eventual consistency because AWS doesn’t offer that", GCP has "we give you strong consistency at scale."
