How is what I said a strawman?
Because I have not argued that the writers of TWOK and STID respectively were working for distinct franchises or corporations; because I have not alleged legal copyright infringement; because my position was about the actions of individuals and had nothing to do with corporations.
Things like call backs and homages are a common tool for writers working in long running franchises
You know what's uncommon? Ripping off a whole scene, just with two characters' roles cleverly switched, even going so far as to use dialogue lifted from the original scene. I don't think the average "callback" or "homage" is so bold as to boldly go there.
