It's a market regulation failure. Which results in a failed market, with the cloud infra provider also providing data services. 20 years ago, there were 20+ widely used operational databases. Now, it's like DynamoDB with like half the market.
How should this have played out in a regulated market? DynamoDB gets released, then what? Has limits on the market share it's allowed to steal?
Should we similarly cap say Front End frameworks on market penetration / growth? Is react too big to fail? Do we need to force some of it's users to use something else?
