I think you've about got it. I don't think this was Apple's attempt to stifle the ability to code on your own computer. They shipped Project Builder on, what, day 1 of Mac OS X? It's more likely that… …this was not super popular, as what's the possible market for an app that builds applets that only work on Macs? Given Mac marketshare at the time, maybe not a lot of hobbyists who (a) wanted to make an app, but (b) didn't want to dive into building a full UIKit application. …this thing was confusing to market. It's hard to give the 1-liner description of HyperCard. …this got dropped because it was not part of the core focus of getting a next-generation operating system out the door. …maybe they didn't actually know how to rewrite it for OS X? Like, did anyone know how the HyperTalk interpreter worked besides the guy who make it?
