You missed the point of those koans. Vim can use external tools like awk to edit CSV and markdown to process markdown. The author was discouraging use of vim itself for things like that.
TED can't show this because they're supported by advertisers, which means they'll never really be free to spread ideas if they go against the will of these companies: http://conferences.ted.com/TED2012/sponsors.php
It doesn't matter whether you agree with a company's technical choices, whether it's Paydirt, Microsoft, or anyone else. If you don't like their choices, you're free to not use their software.
I tried out the Hulu Plus free trial, and I cancelled it within two days. Illegally downloading my tv shows onto a foreign seedbox, transfering them home, ripping out the audio and video from a matroska container, converting audio into xbox compatible format, repackaging into mp4 container, hosting a dhcp server, connecting my xbox to my laptop, then streaming video to it is actually far less stressful than trying to watch them on Hulu. However, if they're on Netflix, I would watch them on there.
Indeed, and I'm not demanding that people be novelists or anything, you just have to master basic punctuation and spelling to make the reader's life easier.
