After some reflection, a PS to argue the other side of what I said above....
Many niche stores (brick and mortar) that I've liked over the years have been hurt by the expansion of big operations (online and off) into their niches. To the extent that small but high quality operations might be threatened by the availability of competitive data... yes, that is a concern.
I think I'd rather have the data given out freely, though, with the intention of raising overall quality, than to have it used to generate lots of cookie cutter junk.
But I realize that it can cut both ways.
