I don't know, but probably the family/extended family? Just have a hunch she was too candid for them when speaking publicly.
I believe that if Lois had something to say that would help bring her baby home that hell or high water couldn't keep her from talking to the press. Also, if there were a reporter out there who had any reason to believe that she was being censored, that reporter would be screaming it from the roof tops. If anybody in this family has been silenced It seems to me it is Uncle Tom. I think that he has willingly stepped back at the request of his siblings. I think that they want to present a united front and Tom as a spokesman just didn't work. I know that others feel he is pulling all of the strings here but I just don't buy it. He is an inactive member of the church and a family like this one would not be taking any kind of marching orders from him. The most likely scenario from my experience with Mormon families is that they are having family councils and working to maintain their united front. In these councils the women would have an equal voice in all matters. I also should mention that just because Tom may not be going to church right now he would still be a part of these councils.
