Well, it's not an OS problem. It's a price/penalty/performance problem.
Some smartass over in the Windows decided they could make things
"accessible" by broadcasting blindly, got something they wanted out of
it, and didn't have to pay the cost. It's kind of like spam that way:
as long as the bandwidth is there, people will use it pretty blindly
and then whine when it gets cut off because of some "feature" they
want.

The damage can usually be restricted by setting up networks on
different subnets, with a network switch capable of doing it
gracefully. Putting the broadcast related services, such as certain
types of video servers, on their own subnet is particularly helpful.
