I think that if post has so trivial amount of information that it can be shortened to TLDR, there is never any need to actually read it

A TL;DR is just a summary, it doesn't need to contain all the information in the original text to be useful.

That's actually how newspapers work though: a big headline to draw your attention, summary to draw your interest and then the body of the article.

You're saying that anything that can be summarised must have originally contained a trivial amount of information?
