why? pride in worksmanship, perhaps... because 1% is still quite a few users for whom the experience sucks... or perhaps just plain old empathy... because not every customer can just replace their device... or... i dunno... just avoiding someone posting embarrassing screenshots of one's app looking like shit on hacker news?
And then you make it suck for everyone else. Mobile first often made the experience suck for desktops. Tiny screen first just makes the experience suck for everyone. The author says: Also, I don’t care if the statistics for small devices is less than 1%, it’s just pure respect for those users. But that's a false dichotomy.
No it doesn’t. iOS’s UI toolkit has numerous tools to allow a design to adapt to screen size. There’s no reason an adjustment for a smaller screen would have any effect on a larger one.
