I feel like it would’ve made sense to include some real examples. Otherwise this just reads very… made up? :'D
Not sure how to explain, but the simplistic nature of the stories you use as examples make the whole text feel a bit like an angry strawman argument even though it probably makes some good points.
I’d even argue just generally don’t drop major spoilers unannounced for older stuff either.
For newer stuff tag ALL spoilers, for old stuff at least tag MAJOR spoilers?
