While there tons of things to rant about in this game, that one actually isn't.Silencers are useless until you get a piece of handheld piece of artillery (how the fuck does a silencer drop 30% of damage?).
To make your gun "silent" you need to lower the bullet's speed below the speed of sound to avoid the sonic crack. By lowering the speed you therefore reduce the impact energy on the target (and range). Read: damage.
Better silencers somewhat do it better, so yeah, that design decision makes sense for a change.
