If you're going to ask people to accept and support your preference for lighter and/or slimmer devices, it might aid your quest if you're not so immediately dismissive of other people's preferences.
Earlier this year, I upgraded from an iPhone 11 to an iPhone 13 Pro. The 13 Pro is noticeably thicker and heavier, and has the sharp slab sides. While these weren't the exclusive reasons why I upgraded, they were a big part of it. I like that the 13 Pro feels substantive and heavy. To me, that makes it easier to hold and to use. The square sides, in particular, are just so much more comfortable than the slippery rounded edge of my old 11.
The stainless steel frame doesn't matter that much to me. I find some of Apple's design touches, particularly with materials, to be sort of silly and fussy for no real gain. But if that extra weight means I also get practical and functional improvements like better battery life and room for better cameras, then I'm all for it and won't shed a single tear for the end of "thin and light" as an endpoint.
I don't have a problem with Apple creating devices that target thin and light for the people who prefer thin and light. I think everyone should have the device they want to have and enjoy to use. But don't assume that's what everyone wants because it was all that Apple made for a while. Now it's my turn to not have to "settle."
