This is what I was basing my comment on in the other thread about, "due to this wicked world our way of worship is soon to change." The problem is they really did nothing but take and didn't give anything. The United Nations submitted their findings to the Catholic Church last year or the year before after they investigated them and told them they have until 2017 to reform their policies to allow contraceptives and teach gay rights in their schools.
The Government doesn't care about whether or not they stop speaking out, they don't want them teaching their followers it's wrong. They want them to teach tolerance and acceptance amongst their community and the Mormons aren't going to do it. So all they've done is said, "We'll still not address the real issue and continue to not comply as long as you stop trying to make us."
They even said it themselves. They will support anti-discrimination laws for gay rights as long as people are allowed to disagree without consequence. So obviously, they still want to teach it's wrong, and its this that the government doesn't want.
