How is that misleading that all they used was “the phone in your pocket”?

I think it does still highlight that you can take this device far, almost as far as you'd ever need to. I think most people making videos are doing it for youtube and social, they would invest in a few smaller accessories that would cover 80% of the needs and would never need to use all of what Apple had at their disposal (the SpaceCam rig is excessive, a lot can be done with amateur/affordable gimbles and rigs). So, it's selling the fact that it's a good starter device for budding videographers (plenty of room for you can grow into it). But also not likely to convert pros away from whatever they're already using.
