They have paid plans which are quite pricey compared to the cost of data. A repository isn't likely to cross the 1 gb threshold easily. They also email you if it does. According to A16Z's podcast or something somewhere they have been profitable since inception so it was not much of a problem. Keep in mind traffic and storage are cheap, and cheaper still in bulker quantities. 1 TB of data is about $30 a month on S3. If each repository averaged 50 mb one user's $7 a month subscription could support nearly 5,000 repos. 50mb is also quite large for a repository btw. If each was about 5mb that's nearly 50,000 repositories that could be supported cost wise with their cheapest $7 micro plan.
