That motion is relative was understood. That even notions like simultaneity also depend on reference frame I think was shocking. And I'm not really sure what it would mean for light to not be at rest in any reference frame but for it to not have the same speed in all reference frames. I think that would be even more shocking than light having a constant speed.
