This also cuts to another aspect of spoilers: there's much more to a comic than particular plot beats. Tone, pacing, characterization and storytelling matter, so a story can feel to a reader that it has high stakes even if nothing of consequence happens to the characters. I can understand someone being bothered if they think that reader's experience of a given story is shaped by expectations driven by the hype. That can lend greater gravity to certain scenes, but lead to a reader being underwhelmed by the final result, after buying a product they would oherwise not.
When Agent Venom was announced as joining the Guardians of the Galaxy before "Darkest Hours" came out, that complicated the promotions. Marvel would prefer fans of the Venom monthly (which lasted 40+ issues) check out that title, but announcements would have to be vague in order to not reveal Venom's fate in Superior. Superior Spider-Man #25 came out in January 2014, while Guardians of the Galaxy #14 with Venom joining the team came out in April 2014, so there was enough time for anyone who's mind was changed due to the outcome of "Darkest Hours" to alter their preorders.
