The article argues that most source available licenses also provide more freedom than only reading the code, such as using it and modifying with some limits.

But "source available", english-wise, sounds like you can only read it.

This pushes some to avoid the term and say open source since that's much closer to their what the license does, even if they are not exactly open source.

The argument is that "fair source" would be a much clearer term for most of the "source available with extra freedoms" stuff, and I agree.
