You're confusing free as in the GPL and free as in beer. The GPL does not 
restrict people from charging for their products, it requires that if you
release the source code for them. 

There is a gray area, not to me but to several large companies, that 
you can release a product under the GPL, solicit modifications to it under
the GPL and then sell the modified code as proprietary to companies who will
modify it and not release the source code.

One company did this and it was well documented, while their product is
still well supported and well thought of by many users, some on this list.

That is very different from BSD's artistic license which says (I'm 
paraphrasing) "here it is, you can do what you want with it".

It also depends upon where you buy it from. RedHat has their license terms,
there is nothing from stopping a vendor from adding their own license terms.
You are free to buy the product from them or not. Requiring you to buy
a yearly support contract may in fact, be part of the license. 

The advantage of the GPL is that you are free to download the source code,
compile and install it if you wish. You can even sell it if you wish,
you just can't call it RHEL. Nor can you call it Solaris, or Bamba,
but you probably would not anyway.

They legally can't. They can remove the logo, splash screens, etc, but
they can not remove any claims of authorship and copyright. The copyright
notices are essential, without them there would be no GPL.
