That's cool, and I'm happy for you that you are in a position that allows you to get income from other sources, so that you can write OS code in your spare time.
Not everyone can or wants to go this way, though, and we got a number of fantastic tools and libraries thanks to people who tried and succeeded in making money from open source. Some folks live off donations, some are paid by their employers to write OS, and some added extra features that allowed them to both offer their tools for free and to monetize them at the same time. It's sad that the last path starts to disappear, at least for some tools. In the end it probably will result in fewer OS libraries, because some number of authors will have to either find another income stream, or abandon their projects.
