Astroturfing generally requires a company backing the movement. Why would a company care enough about pip and virtualenvs and then want to hide that? I didn't see an alternative offered besides using existing open source tools.
It's all genuine, just one guy who doesn't like virtualenv much. I started the blog just to have somewhere to post that. The person who mentioned names probably worked with me.
No other posts on this 'python rants' blog, nothing else on HN?
IMO this is astroturfing ( http://en.wikipedia.org/wiki/Astroturfing )
