Are iPhones overbearing? Sure. But they enable people to stay connected with family, meet new people, work remotely, and more. I'm not against a place that prefers phones stay in your pocket, but why frame it via moral outrage rather than being welcoming? Can you imagine the conversations you'd find yourself in at this place, given this is how the "owner" sees the world?
And maybe what bothers me the most is that it's a blog post. Written on a screen and read via a screen. Blog posts are cheap to write; building a true Third Place is really really hard.
