This is not an accurate representation.  You have the right to modify
with BSD-licensed code just as with GPLed code.  The difference is that,
if you distribute what you've modified, with the GPL you are required to
conform to specific restrictions on how it may distributed, whereas with
the BSD license that requirement does not exist.
