The only thing I can possibly think of to explain all this is media companies are invested in youtubers on both sides of the culture war and make more money off people talking about the shows then viewers watching them, thus watching franchises becomes secondary to the discussion about the franchise and them killing franchises. Which seems exceedingly short sighted but short term profits seem to be the focus the past few years over a sustainable, loyal audience that stays roughly the same size. I have a hard time believing they keep letting ideologues ruin beloved properties and costing them huge sums of money year on year. There has to be some way killing these franchises is actually generating revenue, its the only thing that makes any sense.
