Has anyone else seen this? This seems to be a common pattern lately. Companies will list all their products:

Product X1 Product X2 Product Y1 Product Y2 Product R42 Product F25

… but they don’t have a page explaining what the difference between the X line, Y Line, R Line, and F Line actually are. Let’s say they are gadgets. Would it hurt them in any way to simply say the X line prioritizes speed, the Y line is backwards compatible with legacy gadgets, the R line is meant for business use, and the F line is experimental form factors. How do you not think to put this info on your page?
