Yeah, well. The Dvořáček affair is certainly a serious allegation. Yet not something the general public can be a judge for. Given that the Czech authorities and courts did not pursue it, the rest of us can't either, if only for the lack of information.

As to the rest of it — authors routinely revise their works. The very notion that readers (or critics) get any say in this strikes me as bizarre. They get to observe the process and decide which version they like better, but nothing more. Ne supra crepidam.
