I understand your sentiment, but a lot of that isn’t right.

Early iPhone apps were going for $10-20. So many developers being okay with just data harvesting plus so many devices out there made the $0.99 / free with ads model dominate – people got used to “free” apps from the big guys (Facebook, Google, whoever).

iOS apps are pretty resilient to OS updates. They usually only totally break when huge changes happen (dropping 32-bit support, etc) and those happen once a decade.

Tons of Windows software didn’t survive the 3.1 to 95 transition. A bunch died on 98 to XP, too. In the Apple world, a lot got left behind on the Mac when they went from PowerPC to Intel processors in 2007, or when they dropped 32-bit libraries.

In the revolutionary context, the extra days were all piled into the end of the year. Kind of a special short month, or more realistically a set of days not in a month. But yeah, leap days were added there when necessary.

Twelve months of five weeks of six days plus five or six days at the end for Christmas and New Years would absolutely rule. As long as weeks became 4+2 and not 5+1, anyway. I say we drop Thursdays and just keep the rest of the day names, they’re fine.
