Why can you AFK the entire Radiant Echoes event and get full loot credit?

I see we have the white knights of Blizzard defending afk’er getting all kinds of drops off the current event…very typical of the lazy players in this game anymore…we saw it happen with the Cooking Event with the Tuskaars…seen it with the digging event…as long as I get mine and I don’t have to shoot one mob its all good…screw the players that actually do event the proper way now…
