@mDiPalma funny because you're also meant to know the law and yet people "bend" it all the time and get away with it. Or else they go to court and a judge makes a decision one way or another, and often it goes against what the wording seems to be. Then these things get challenged through the courts, all the way to the top, where some small group of important people determine how we should "interpret" what is written, and this generally results in a new law, or at least a new interpretation of a law. What I'm trying to say is in practise legal interpretivism is generally used.
Also you blatantly ignore the Mission Statement of the WCA, which trumps all regulations (after all, the regulations are there to guide us towards the mission of the WCA). Now I know what you're going to say "fair and equal conditions" blah blah, but this is all open to interpretation. We use different scrambles all around the world every weekend. Hell, we use different scrambles in the same competition. In the same round. Sometimes just for one person. Nothing is different about this case in terms of "fair and equal" other than the "random state" thing, which then brings us back to the interpretation of the mission statement, which the WCA Board has interpreted in this case to be in favour of keeping the solve.
Your options are thus:
1) Keep on hating it. In this case I suggest you leave as you are in the minority and clearly your values aren't compatible with the WCA, and no one is making you stay.
2) Accept it and move on. Please. I wouldn't want you to leave over this, but that is up to you.
