I understand where you're going, but does that even matter at this point? HG wins either way, because people who look at it in that way, or any obscure or long winded way that rationalizes fluidity in the Robotech universe, raise it's credibility as something beyond three shows edited together. The difference is that HG doesn't have to do more work filling in the gaps to get audiences to believe it, fans do it for them. The illusion remains and HG maintains an audience to bait into believing, and buying, anything.
As if stuff like integrity, morality, and creativity matter to these people anymore. HG just needs people to believe in their work and the Robotech label, nothing more.
