They openly deny that the law must be kept, but then imply through their crafty words and practiced deception that it must be kept in order to be saved (by saying those who are truly saved will keep the law)
So if you are saying there is a law that is being preached it is not this.
In terms of righteousness, the apostles do say we walk in righteousness.
EG argued months ago people in some churches end up with lists of behaviour not acceptable, and behaviour that was approved. They failed though to love and so ended in legalism. Legalism can happen anywhere. I can go to church because I always do, or because I love the Lord and expect to be spoken to and to share.
It is true some have said any list of morality is wrong. The problem is the apostles made such lists, and lists of expressions of life that were commendable. So we are called to obey and to behave in particular ways.
Now this is the fruit of faith, but I do not understand your suspicion without evidence. I have not read such statements, and I personally have provided known, as far as I know.
Jesus was continually accused of being a law breaker, but was not. They said he did miracles by the devil, but he did not.
As I keep saying if I say, "I keep the law of righteousness by the power of the Spirit" but not "I keep the law" is not.
You have to give people some leeway of expression, else it get very legalistic.
