Hope springs eternal but I think people are missing the constraints Cigarman is working under for all these suggestions to make sense.

CO has shown no inclination whatsoever to change anything that either costs them money or reduces revenue (and I am sure for very good reasons from their point of view) immediately. Keep that in mind and go through your suggestions again to see if any of them make sense.

Many have pointed out indirect costs related to revenue-earning or cost cutting policies as in lost business, etc. That is a tenuous argument at best and unless people here or Cigarman are able to quantify it and present it as a verifyable business analysis, they are not going to consider that over their own op research for these decisions.

What Cigarman seems to be able to influence are "hygiene" kinds of things. Errors, bugs, improvements in process that have been sidelined and may not have been addressed without prodding. While anything is better than nothing, these kinds of changes (i.e., primarily attention to detail) are what would differentiate an airline when the going is good but hardly sufficient to mollify when the problems are much more basic and bigger at least as far as OP is concerned.

If these are not the kind of changes that you have in mind, then you need to find other means to influence CO. Walking out in a fashion that affects their bottom line and visibly tying that decision to one or more of their policies is about the only valid approach.

Just to bring a bit of reality into this....
