I guess I shouldn't be surprised, but I always am: there's a really strong impulse in the photo community to conform. It's never said out loud, but look around a bit and you'll get the picture.
You'd think it would be the opposite: "I see a lot of zigging, perhaps I'll zag." But it's not. Zigging leads to more zigging.
I could be wrong, but I feel like photographers a few decades back took more pride in being out of step with the trends. I also feel you saw more "weird" images, and more breaks from the expected.
