There is no other interpretation. "not enough" implies there should be MORE, which is a requirement. The requirement is never elucidated. This is a Mazouz gripe post for OSS issues that are not unknown, and provides no insight.

All code requires effort to utilize. Proposing that OSS should have some additional (hand-wave whatever you imagine) requirement lowers the effort to utilize it in some way and that result differs for each program. Imaging OSS code that simply does not compile. What more can you ask? Homogenization of code is a Sisyphean endeavor. The best we have to a uniform interface is source-code text.
