I've always had the same issue as OP - it's never bothered me much because I'm rarely in the mood to read something so dense.
But I find it quite interesting that I've managed to completely miss the big obvious blue buttons every time, I just immediately scan down to the first paragraph.
The cynic in me guesses it's because I'm so used to extraneous content taking up space that I instinctively skim past, but maybe that's too pessimistic & there's another UX/psychological reason for it.
Its the idea of the gateway: we click on a link and expect it to be what we are looking for. Having some "summary" or paywall or anything between us and what we thought we are getting is , QUICK CLOSE THE STUPID WEBSITE as fast as possible triggering.
