Yeah, it's definitely not right in the details. Maybe I shouldn't have emphasized "ever" so much. But my goal was more to dispel much bigger misconceptions that went into the question rather than cover all the little details of how these horizons work.
I don't think there's really a good way to answer these complex questions that were formulated based on a lot of complete misunderstandings of what these words even mean. At least not while still sticking to just words. But saying "nothing will ever appear to be moving at C from our point of view" was probably a bad choice. But it would be true if the hubble sphere never changed in size.
The fact that we can see light from galaxies with recession velocities higher than C is one of those facts that is truly awesome to point out, but is pretty much guaranteed to just confuse someone who probably has only learned about cosmology through popular science.
