I don't understand the aversion to python here. What is it about python that makes it less reliable than any other piece of software?

Yes, downloading hosts files from 3rd-party sites is kind of sketchy. But using python to do it is what you're worried about?

I mean, if you don't trust the sources, you can use your own. Or if you don't trust the software, don't use it. It's up to the end user to decide what is in their best interest. I believe the included lists are trustworthy and I use them myself.
