> I don’t agree with much in this writing other than that eventual consistency is a bad choice

Does it really matter wherever is bad or not? As far as I know, every database that scales beyond a single node (for performance) is eventually consistent. Otherwise you've gotta wait for a sync between nodes before a response can be given, which would effectively force your cluster to have worse performance then running on single node again.

There are a bunch that offer strong consistency e.g. Cloud Spanner and DynamoDB.

Don't forget FoundationDB

That's SO not true. Spanner, Amazon's S3 are some of the biggest databases on the planet, and they are strongly consistent.

Yes, you are trading latency for fault-tolerance, but so what? What if the resulting latency is still more than good enough? There is no shortage of real large-scale applications where this is the case.
