Yes, I forgot that this package repository is hosted on python.org, and it
really is a problem. I thought it was hosted by someone else.
> I don't think the fact that some software in PyPI is proprietary is a
danger of Python, specifically. Proprietary libraries exist for C, too.
The problem isn't that non-free Python libraries exist, like with C, but that
they are hosted and maintained on python.org. People who like Python may
also think it's a good idea to install those non-free libraries. It's
similar to the Debian problem - although Python doesn't install non-free
software by default, they are still distributing it and in a way recommending
it.
Maybe I should look more into GNU Guile. :)
