> Starting Strength fails in teaches the idea of deloading by dropping weight then taking a run at it without changing any of the training methodology

No, starting strength tells you to take exactly two runs up until your failure weight and then move on to another program, which for many people works very well and allows them to progress far beyond weight they failed at. People who can run an SS linear progression for a year straight are rare, but they exist and they end up in the upper 3s, 4s and 5s for bench, squat and deadlift after their first year.
