It's not my problem if people don't stay current on media.

And if someone cares that much about consuming something that already exists in another form... maybe also be curious enough to consume it there?

I'm certainly not going to censor myself for people who are a decade+ late to the party and refuse to read a book.

What do you mean, ~problem~?

Nobody is asking you to censor yourself. I am simply asking you to preface a plot spoiler with something.
