Neither of those are true, however.

It is being used by Facebook, Metlife, Expedia, Sony, eBay, Adobe etc.
In what way isn't it ready for production use cases ?
Your parent commenter doesn't like Mongo. So it's not production ready.
Eh I don't like Mongo because I've used it. IDK, it's been a few years since I've had to deal with mongo in a production environment. I don't miss it. I dislike that it's slow to get data to/from the javascript interpreter -- and that the solution was to work around it with the aggregation framework.
I don't like the unsafe defaults (data integrity, access control).
I don't like the magical, unreliable sharding that you have little to no control over.
Sony is a worldwide company with 127,000 employees, they alone probably use just about every database system around. So saying sony uses mongo isn't impressive, for all we know it was just a side project from an intern that has 100 documents, there is no context.
Well I have worked for a number of billion dollar companies who have run MongoDB so there is first hand evidence.
And how is that a paradigm shift? Non-relational, non-SQL databases have been around for a long, long time.
