They could be a hero by placing them in the public domain. Licensing them for even a nominal fee would be extortion. $1 for something that should be $0 is an infinity too large, besides it would still require you to get that license.

If someone were to charge me 'right of way' tomorrow to leave my house and the cost would only be $1 I wouldn't pay up, I'd shove them out of the way. There is not 'right' price for extortion.
