Not only that but every single update you push requires paying $$$$$ to get certified. It is freeing that the cost of releasing a fix or improvement to a product is $0.

In the past I considered selling a custom adapter to hobbyists, but all the certification costs just did not make it a viable option to pursue. I didn't want to up front thousands of dollars to make like $100 if I was lucky.
