Oh I agree with the heavy handed threats. That's horse caca in my opinion. Please note, that my xh has said some crazy things including he would just disappear and never use another electronic device (haaaaa!!!!) if kids did not do x. I consider myself flexible and fair, although I no longer engage with nuttiness.
Tar, I totally see your sitch. I do. The only thing is that it feels in a way that you are trying to teach your W a lesson. I understand that she is "picking and choosing" what works for her. And she wants it her way. I get it- I do :-) I just think that your kids are old enough to speak their thoughts and feelings to their mother. I witness that frequently with my kids to their Dad and while it's sad, I also find it necessary for their benefit. It's a sticky sitch no doubt and just love and support your kids. That's all. There is no *easy* fix to their pain.
Hang in there!
