A great deal of why anyone still cares about Flash is the huge amount of amateur animations & games that were made with it.
Much (most?) of that was made with pirated copies. Is there a way to use Animate for free?
I doubt Flash would have been half as prominent, nor that we'd care about it half as much today as we still do, if they'd had some kind of perfect, flawless DRM on it.
People who were subscribed to CC would have been upgraded to Adobe Animate and could have kept using it but it seems they didn't.
