Honestly I don't see a problem with it *as long as it's an option and only an option*. (I'll admit my ADD kicked in half way through a 5 minute video so I didn't watch the whole thing, and only followed part of what I did watch.)
Me, I like owning my stuff, as I'm sure many here do. It lets me customize it the way I want, everything from a little $300 NUC that I tossed my own SSD into up to and including my car. Plus it has the added long term benefit of not having to return the thing and worry about every little scratch, scuff, and bump.
But, as mentioned in the part of the video I did watch, "leasing" a phone is very similar to leasing a car. It lets you get "The Shiny" you may not be able to afford outright, and you get a new Shiny every few years. If someone trades in their phone every 2 years anyway and Apple prices the program right, those that take advantage of it may break even and/or come out ahead (though I doubt the latter).
