Maybe because it's harder to learn. The R-slice targets are even more troublesome than M2 M slice targets and you need to learn a few more algs. For most people, who probably don't care too much about BLD, OP is fast enough.If M2 is a pretty popular 3BLD edges method, why does no one use R2 for corners?
People who do care about BLD probably just go from OP to 3-style directly, which isn't that hard really. R2 is useful though, if you want DFR as you buffer (which is actually a pretty good buffer).
As for people who care about BLD and use R2, well it's like using keyhole F2L because you can't be bothered to learn proper F2L. Really, switch to 3-style already.
