Competitive SR points

Dear Blizzard!
I cannot understand one thing in competitive.
When you lose a match, you get -15/-25 points in most times, even if you are on a losestreak. But if one of your teammates leaves a game, no matter if he’s just salty, or DC’d, you lose 30 points. (And get less points if you are in a winner team) Why you punish the team of a leaver? Beacouse they are not good enough to play 5v6 or what?

You lose 50sr if you DC or simply leave a game. Also competitive points are the purple ones not sr

Yes, you lose 50sr when you DC or leave, but why the whole team is punished for that?
