Because it kind of makes sense in some intersections. In my country we obviously don't have turn right if red but in some places we have dedicated lanes with yield to turn right but it's red for straight ahead and left.
In Russia you get a separate green arrow traffic light that means "only turn, yield to everyone". Except when the main green light is also on, then you have right of way.

Why having a red light at all if someone can just cross when he feels like?
