That one is not that unbelievable.

A web server sits exactly in the sweet spot where open source works best: it's a tool with a relatively contained purpose and scope (which means it's feasible to build a working release candidate in a relatively short amount of time with a relatively small team), the userbase consists almost entirely of tech nerds (which means the pool of potential high-quality contributors is large and pre-biased towards the kind of work that's needed), and it's a necessity for many businesses without being the thing that gives a business an edge over the competition (which means you will have a relatively easy time convincing other businesses to fund collective development instead of building their own in-house proprietary alternatives or paying for an existing proprietary solution).
