there is no way on earth pypi traffic is higher than wikipedias.
pypi servers receive 1 million requests per minute. That's likely more than wikipedia.
According to Wikipedia's public statistics[0], they receive ~3 Billion media requests per day, which is about 2 million requests per minute.

en.wikipedia.org has around 260 million page views per day. Each page view consists of multiple HTTP requests (picking a few random pages shows twenty or more per page) - so I'm pretty sure that wikipedia has higher traffic figures.
It's kinda moot though. I wouldn't begrudge pypi asking for money either.
