You are again confusing the Standard with implementations of the
Standard. The ATSC does not build hardware. But they did write a
standard that is extensible, as history proved. So, if there's anything
to complain about in this regard, complain to the CE guys, not the ATSC.

Why not? What's so hard about creating new services using A/90, for
example?
I see nothing stopping both the ATSC and the DVB-T from merging into one
standard. DVB-T has already taken a step in that direction, to support
US-produced HDTV shows. That's when DVB-T included 1080 at 60i/50i and
720 at 60p/50p to their bag of tricks.
It is not so difficult to add the complete DVB-T set of functions to
ATSC, without having to change the physical layer. It is probably also
feasible to build COFDM/8-VSB demods, to allow a smooth transition, or
just complete interoperability. Combined tuners and combined decoders
are already in production, so only the combined demod is needed to
achieve this global standard.
