It's still seen as a waste of time, I think. Just has finally been accepted as normal. And while you may have been firing up hex editors, that probably wasn't the norm.
YOu are right, though, that the computer games of the nineties offered a lot more hackability than iPhone apps. ZZT was an introduction to OOP for many kids, Red Alert had rules.ini that defined the stats for each unit, and Duke3D had configuration files in C. Mods and "Total Conversions" were a things. That ecosystem isn't just unavailable in mobile games, but would probably be hated by many companies who want full control over their product.
So two things we should do: write more moddable games, include defaults that don't assume we're all male (or white, for that matter.
