Open source is mostly objective, unlike 'good software'. The parent comment stated in caps that MongoDB is not open source, which is objectively untrue. It's a silly thing to bicker about, but the original should have probably said something along the lines of 'OSI approved open source license'.

The only objective definition of Open Source I know of is OSI's. Everything else is a hodge-podge of whatever the user of the word feels it's open. Is it reading the code? Modifying it? Redistributing it? There's no consensus besides OSI.

But their definition does not restrict it to OSI approved licenses, so their assertion its not open source because it hasn't been approved is not valid.
