A lot of copyright licenses say "if you change this, rename it"; I think
the old Apache license[1] is the biggest source of this.  It's a flawed
approach, of course: since it only applies to derivative works of the
program itself, people can still create an entirely original work and use
the name, which is why trademarks are the only "secure" way of doing that.
