Why is Disney putting out so many spoilers???

Rating: 5/10 (1 May 2019)

I'm going to see this movie ina couple of hours. And while no one has spoiled this movie for me yet, I don't know why they are airing so many spoilers in TV spots? First the trailer shows Tony stuck in space, and now the TV spot shows Tony with the other Avengers in those white stormtrooper like suits. It tells us Tony survived Space. Also they put out the trailer for the next Spider-Man movie so we know he comes back (as expected).
So knowing all this I'm gonna go watch this in IMAX 3D, and I'll add my review to this post once seen.
