Realistically that's not going to happen unless they can pass on the physical books and/or their scans. They might bother paying for a basement-full-of-crates "library" if they got to put the PDFs online and brag about preservation. Same deal for dumping truckloads of obscure nonsense onto local libraries and loudly scoffing at critics of that let's-say-charity.
But under the rules they have to follow, what they're doing is obviously what they were always going to be doing. They only want one copy of each book ever mass-produced. They're scanning them in the easy and fast way that also solves any legal concerns. They kept it quiet because people predictably flip out over this wide-but-shallow purchase.
Their actions are unlikely to change unless the legal situation changes. Let's maybe change it for the better, for all of us.
