Yes, there is a theoretical risk that the FSF be taken over by some
evil empire or other. I do not know the full details of the FSF's
charter but I suspect it has built-in protection against that sort of
thing. Also, as part of the copyright assignment process the FSF
guarantees that the software will remain free. So even if there was a
hostile takeover, it would be legally rather difficult to turn any of
the assigned software proprietary or anything like that.
Spread copyright has its own risks. Suppose that the evil empire
instead "persuades" various politicians to pass some new software
copyright legislation which, as an unfortunate side effect, makes it
illegal to distribute GPL'd software. There is nothing unusual about
big companies lobbying for legislation, e.g. the music industry. In
this scenario, the FSF could tweak the GPL license for all assigned
code to work around the damaged legislation, to the best of the FSF's
lawyers abilities. Now consider a project with spread copyright like
the Linux kernel. It would be necessary to contact every contributor
and get them to agree to a licensing change. Any code where the
contributor could no longer be contacted, or refused to agree to the
change, would have to be taken out and possibly replaced. Until all
that had been sorted out nobody would be allowed to distribute the
OK, there would be legal challenges, workarounds like distributing the
kernel from another country with different laws, etc. Still, having a
central body holding the copyrights does make it a lot easier to
respond to such legal issues.
