According to there is
for Bison:

As it happens, Bison can also be used to develop non-free programs. This
is because we decided to explicitly permit the use of the Bison standard

decision because there were other tools comparable to Bison which
already permitted use for non-free programs.

flex appears to be under a BSD license.
