I would call this MongoDB'd themselves. Except that also would imply that people are still interested in MongoDB. I think their license move probably just accelerated the decline in interest in their product.
Mongo adoption has risen at a rapid rate, and cloud services now make up nearly 40% of their revenue (which, in turn, allows the company to push those $$$ into the core product). Your statement, while a common view on HN, is not correct. Just because tech bros have moved on towards other interests has not meant that adoption of Mongo has faltered.
