No, the proposed regulation has not changed. These regulations were released last month, and they have not been altered by the DOJ. It is actually unlawful for the DOJ to do so after it has been published in the circular.
What you must understand is this: What the DOJ is going to say vs. what a good First Amendment Attorney will say are going to be two vastly unique and adversely different things. You can not logically expect the opposing side of the argument to say what you want them will say. I do not want to be redundant (and I am fucking tired), so reference my previous post for the 4 major reasons (I could think of at the time) why text only TGPs have very little to worry about initially.
Beyond that, your best course of action is to speak with a good first amendment attorney and follow the guidelines they give you.
Does doing so completely exempt you from potential litigation? No. The reason being this: Most of this is up for interpretation. It WILL take litigation to better define the grey areas, unless what is released tomorrow @ 1:30PM somehow manages to negate what I've stated here.
I highly doubt that will be the case.
Regardless: If you'd like to read more of the 2257 Handbook we were given, have at it:
