Don't think so deeply about it. They didn't want to nerf silence or CC in general. They just wanted to remove silence from assassins that can burst you within the duration of that silence. Why? Because it gives no couter play, seeing as you can't actually use disruptive skills during that silence.

Slows are something that give you time to use your skills effectively, A well prepared foe will not really be that bothered by it. They are a form of soft CC that don't really hinder your foe, but does help you land skills. Unless somewhat iconic to the character ofcourse, Sejuani, Ashe and Thresh for instance. Otherwise think of it as a QoL thing, Trundle's slow, Now talon's slow, it just helps them get off 1 more auto attack that might make a difference.
