I'm pretty sure there are no spoilers in that first paragraph. In fact, I'm pretty sure most of what's referenced was available in pre-release materials (trailers, press events, and such). I just saw the movie and just read this article, it's less spoilery (in my opinion, not spoilery at all) than listening to coworkers in the lead up to it who were making conjectures based on their knowledge of other Star Wars media…
Pre-release materials are the worst, and often contain awful spoilers. I intentionally avoided them for Star Wars. During the previews when I saw Star Wars, one of the people I went with did his best to ignore the Captain America trailer, because he didn't want it spoiled at all. You watch enough ads/pre-release materials to decide you want to see it, then once you decide to see it, you ignore everything you can.
Again, I'll except trailers for thrillers and the like, those story structures necessarily depend on twists or slow reveals for their ride to be fun or interesting, and a spoiler can absolutely ruin them. But action movies?
