This is a highly misleading characterization. FreeBSD never imported any
GPL3, which resulted in a toolchain that is for many purposes useless in
the base system. It is now slowly coming back to the point where it can
be used.

The situation in NetBSD is effectively:
(1) GCC which has a runtime exception for the libraries that removes the
immediate problems of the GPL3 vs the earlier GPL2 + runtime exceptions.
(2) GDB which can be easily dropped from the target system.
(3) Binutils which can be easily dropped from the target system.

That was the pragmatic choice taken in NetBSD -- keep using a toolchain
where we don't have to fix all bugs ourselves, but which can be mostly
segrated for deployment.

Please don't talk about things you have no in-depth knowledge of.
