The reason they provide it free is to encourage people to visit their website. Giving it away to your friends means that they don't get the exposure they were after. They will not be inclined to offer fonts for free again if this happens.
I find it very disturbing that there is a view that if something is free, that it does not have copyright attached nor was it a lot of work for a designer. This is not true, and it is damaging a lot of very talented people out there who are being very generous. Is it so hard to support those designers that make available some of their fonts etc. for free?
