"Holding their phones wrong" — you mean, holding a rectangular affordance ergonomically in their hands?
The odd thing to me is that you can't just tell your vertically-oriented phone to produce landscape video. The imaging sensor is square.

You can see that in any teardown.
I do agree there's no "right orientation" though since it's subjective. However having a square sensor would be illogical
Now, you could argue that we've gone more mobile, and newer social media formats expect portrait, but, that doesn't change that it's risen because people take videos and never consider, "hmmm, if I turn it around, I get a better picture and it looks more like a TV! Duurrr." Just because it's more popular doesn't mean it's not stupid AF.
