Because some folks need to find out about Angel and radio's one of the few ways to make that happen. Otherwise normally folks like Giles and Paige wouldn't know that Angel was sick in the first place.
There's other ways to make that happen if we need to though. Like radio could hold off until the UK folks are gone, or we could figure out a way to grapevine it.
A possible quick and dirty solution is that the Fri night stuff is NFB but anything on Saturday is fair game. That gets the UK gang out of town and still provides a way for others to hear about it in a fairly timely fashion.
