It's easy to forget how popular flash was in that decade. A lot of us found it annoying on desktops too. Not to mention Linux, where we'd deal with binary blobs that were pretty unstable, not because we liked it but because you needed it to interact with the world.
I have not so pleasant memories of having a few different versions of their plugin and I'd try to figure out which one worked for a given website, symlink the right one and restart the browser. And that was the way to watch videos online...
Flash as an animation tool and applet platform was already on the downswing when the iPhone happened, though.
The consumer demand for Flash on mobile seemed to be mostly about video streaming, because at the time Flash was experiencing sort of a second life as the least-bad way to do streaming video on the web. In that context Apple's point of view of "as an industry let's finally fix browser-native video streaming, rather than being stuck with Flash forever" seems pretty reasonable.
