I want to afford anyone the benefit of an F/OSS license so they don’t have to waste their life energy recreating a wheel that I’ve already created. If it helps you and saves you time, have at it! In other cases, I contribute back patches so that companies can ship better software to their users (sometimes so I benefit; other times just so someone else doesn’t have to fix the same bug I just fixed).

This license case isn’t about “you can personally monetize it and nobody else” but rather “you and anyone else who wants to can try to monetize it”.
