What is the rent here, enterprise licensing? Quasi-monopolist? Does MongoDB have anywhere near a majority of market share for database vendor?
In technology, it's often the cost of re-integrating with something else. MongoDB makes this lock in ever better because it's API isn't SQL, so getting off is even harder than usual.
It's pretty easy to use the Mongo protocol to talk to Postgres, and Postgres JSONB beats Mongo BSON hands down

Cue gratuitous protocol changes from MongoDB.
Spot on. And this rent-seeking behavior is all about becoming quasi-monopolist in a niche and it's anticompetitive and anti-innovation.
Real R&D is done only to capture land, then it is replaced by PR and all efforts go into holding the trench.
