PSA: Surrender Is An Option. It Is Not The Only Option
Surrender is NOT there for you to be pouty at 20 minutes because you died twice and the jungler "won't come help you" because you are pushed up all laning phase dying to enemy ganks.
Surrender is NOT there for you to threaten people with "surrender or I afk" when you don't like the champion they picked.
Surrender is however there for when you are about 20 kills, 4 towers, and every objectives on the map down, but refuse to "give up" even after someone rage quits and the enemy has taken down all the inhibs.
An obviously lost game (not a close game, or some kills down at 20, I'm mean like all objectives and double to triple your kills) game is a good time to surrender. Raging because you can't handle dying twice in 20 minutes is not a good use of Surrender. People need to learn when not to give up and when to call it a game and try for the next.
There is no shame in surrendering, and there is nothing wrong with having a bad laning phase and letting your team carry you if necessary, or play for the team fights and objective game (or split pushing). You aren't going to suddenly get a shot at joining TSM because you never surrender. You also aren't going to get into the LCS by giving up at 10 minutes in and pouting.
Surrender -option- is there for a reason. Use it, but don't use it as a threat because you can't handle losing.
