Is he actually? He only "has" two projects that anyone cares about to my knowledge.

He meant it in terms of calling people stupid.

Two prolific projects that amount to far more than the vast majority of us of is will ever accomplish.

I suppose "prolific" does not necessary imply breadth or depth.

I believe an operating system typically implies both.

Prolific typically implies many things. I have a deep respect for linux and git, but neither are really prolific.

Anyway, I thought the OP meant he was prolific in his tirades, which is very true.

The way I interpreted the word was more "doing lots of things" and less "doing lots of a few things". Either is legitimate in retrospect.
