I think of this as belonging to the same class as electric cars with software-simulated clutches and transmissions.[1] BYD makes a driver training car which is an EV with a totally simulated stick shift and clutch.)[2] The trainee can try grinding the gears and stalling the engine, but it's all a software-generated illusion.
There's no illusion with a DVS setup, latancy is so minimal you effectively have the exact same fine control over the track as you do with a standard record.
That's not a good analogy. Mostly shows you don't understand the problem being solved.
It's not "faking" an analog system within a digital system. (If anything, that's what a full digital DJ set up is.) It's an adapter between the two.
As such a purist, would you prefer that digital music is never used? Or that digital music must only be used with digital controller? In that case DJs that use both types of music have to lug around two separate controllers.
This may be a better explainer than the article: https://www.youtube.com/watch?v=d7OgQJ2r0RI
