Think it's a UK / US tax authority issue, nothing DEC can do to change international tax law. As per previous comments I'm sure your broker has some advantages, obviously dealing with US firms is not one of them.
It's nothing to do with being silenced, your experience is a minority one and not shared by those DEC holders who use a broker who, for whatever reason, can sort out the US tax issues.
