[entuno]

Does this same argument not apply to other areas of music though? By that line of reasoning, should sites not also have to declare whether they used synthesisers rather than real instruments, or autotune for vocals, or all kinds of other things like that so that the listeners can make informed decisions?

I don't think any consumer would object to that. Typically the instrument thing is already handled in the "liner notes" (or the digital equivalent). It'd be nice to see a disclaimer for auto-tune as well.
