I think this is right.   A lot of what I am seeing here as examples are 
situations where someone with some technical know-how and a bunch of leaked 
info is able to give an end-user help that they otherwise would have not been 
able to get without the help of their service provider, with the result that 
the end-user continues to use the service provider that has utterly failed them.

What should actually happen here is that the end-user should say "huh, my 
service provider isn't helping me, I should switch to someone who provides 
better service."   By making it possible for Marlin B. Rando to diagnose their 
problem (at the expense of _everybody's_ privacy), you are not really helping 
them.   You are short-circuiting a feedback channel that would, if you didn't 
short-circuit it, actually do a better job of correcting the problem.
