While I have no proof of it, it does seem like the advent of social media has made people more hypersensitive to spoilers.
While my dad famously never wanted to know anything about the movie he was going to see aside from the start time and theater number (he did not even want to know the title), this was most apparent to me in 2019, when I saw a little movie called Avengers: Endgame. One of the biggest cinematic events of my lifetime, I was unaware of the fact that just mentioning the fact that the film dealt with time travel spoiled it (at least for a friend of mine).
Nothing else to say
