red hat enterprise is like 2000 bucks
and it is well worth it.
2000 bucks is not free.
also ... go to compusa, you'll see at least 5 differnet linux distros for sale.
oh, and its not obsurd. think about it ... its kinda like p2p sharing.. if you take and take and take, thats not right. you need to give AND take, and the community will grow. the more you give the better. if you use linux, you should donate to your distribution, whether that be money or donate your time and expertise in software development. dont just take, give as well.
