The hippies writing that software may not be compensated at the level you'd expect given the value they provide, but they'll never go hungry.

Stuff that ships on a Canonical desktop or RHEL default install gets lots of cash but community favorites like KDE need to make their own way, etc... Also just to be clear: node is filled with povertyware and you should be extremely careful what you grab from npm.
