I don't understand the sentiment of this at all. It's fun to create things, I've learned the most from working on "toy" projects, it helps with job burnout, and could potentially become a new product/company/revenue-source.
If You don't like the idea of my project, You can just ignore it. I spent my free time to create this and I'm happy, that someone likes it. I train my programming skill and learn new thing by doing projects like this. I would never learn programming if I didn't play with it.
