Of course, when asking legal questions of a user's group, the resulting
advice is worth at best exactly what you paid for and at worst, there's not
Now let me tell you my half-cocked <= $0.0 interpretation.
Yes, the BSD language isn't completely clear and could be read in a way that
BSD is a bad bad viral license invalidating and making free anything you've
ever done or thought of doing. You will find user group discussions to this
effect if you spend too much time on the web as do I.
However, the clear and commonly understood intent of the BSD license is:
Make hay! Use and abuse the code any way you want.
Many big companies with their buildings of bored corporate lawyers seem to
use BSD and interpret it in the make hay way. Berkeley itself holds this
view (so I've read by someone who's grandmother told her that she heard it
from someone who knew). I suspect that most uses of BSD code doesn't even
include the BSD conditions. A bunch of things that use OpenCV don't include
the BSD verbiage and one day I intend to hold absolutely ... none of them
accountable. I can't speak for the ROS developers, but I've seen them
shudder with religious ecstasy every time someone even thinks about using
ROS ... so I'm guessing they'll let BSD slide.
