If, like many people, you need things shoved into an imaginary concrete, low-dimensional, binary box: "the type of person maintaining an OSS project can trivially make >$30/hr[1] on 10 hrs of contract work a week". If you still think this is too subjective to infer anything from, enjoy your onanistic "nobody can ever really know anything maaaan" perspective, but it's not really relevant to this conversation.
