Since close source drivers violate the Linux GPL, distros like Red Hat force
users to download and install the drivers separately. So technically the user
is the the one violating the GPL not Red Hat Inc.
The other solution is the binary BLOB where a closed source device driver is
converted to an unreadable and uneditable open source blob and linked to the
kernel. Technically its "open source". The legality of blobs is in question
too.
