This seems like a pretty reductive take. An Ubisoft-sized company, having all the relevant data and having a huge incentive to learn everything that can be learned from it, is surely going to have some idea of the scope of the problem.

I mean, tons of people on this page are saying DRM doesn't reduce piracy and serves no purpose. But it's hard to make that position jive with the fact that the companies with tons of data on how DRM affects their bottom line keep paying for it.
