Very true. In case anyone is too young to remember, in the days of the iPhone 3G, it was somewhat popular to buy apps which would use a real browser on a server somewhere to render a browser session, complete with Flash, and stream it to you. It was very handy for those of us who played Flash games and needed to check in on our game on the go. (Think FarmVille, Cityville, etc.)
There were some 3rd party things that sorta worked a bit, but they were not good either.
Flash was bad on touchscreens for sure, but we’d have seen content adapt eventually anyhow, if it had actually ever worked in the first place.
