Choosing an Open Source License

For anyone who still doesn't think licenses are a big deal, I would wager that you have never:
a) worked for a company with > $1B in assets
b) worked for a startup that might be acquired by a company with > $1B in assets
I think that what is allowed is highly dependent from the laws you can or want apply. There is a vast difference between what is allowed by such a short statement in the US or in UK or in Germany.
That said, I'm not sure if downloading the source from Github constitutes any form of reproduction or distribution. From what the page you linked to says, that may be covered by Github terms of service.
Copyright does cover use in many (most?) countries, especially EU countries.
This difference between US and EU author's rights has been widely debated for the JSON licence that states "The Software shall be used for Good, not Evil.", making it a non-free licence because it restricts the field of use.
