Those who have contributed to Linux have accepted that fact that everybody
may make money on base of their work by madifying Linux. Modifying
Linux means implicitly accepting the GPL. One the one side that's a
legal thing to accept the GPL. The other side is the moral part. If
they cannot live with the GPL then they shouldn't accept it. Oh, and
the third part are those who haven't contributed to the Linux effort
but have a opinion regarding making money based on Linux. Whatever
their opinion is, I ignore it at least in that respect.
