> If the work is any good it will work with or without knowing details just the same

Counter example:

Only because the twist of the actual reveal of what project Horizon Zero Dawn really was (in the game of that name) did it become a very emotional moment for me. I had to stop the gameplay video (I never play games, I watch the stories of story-rich games on Youtube) and cry for a bit.

Surprises and "reveals" can be important.

I agree with spoilers found in discussions about a work though. One has to expect finding them there, and it is easily avoided by not reading a discussion about a work before you read or watched it.

Personally I agree. You only get one chance to learn something for the first time. But of course the central mystery of a whole game is a much more specific and interesting spoiler than "someone in the story dies, probably", which is the alleged "spoiler" I started by asking about.
