Are we talking past each other? It seems like we just disagree on when segmentation on SSO will no longer be prudent - I believe we’ve crossed that point, and you believe it’s in the future. Seems like we agree in substance though.
If it's actually true that we have crossed the point where it is no longer prudent for companies to segment their customers this way, then there are a whole lot of companies making unsound business decisions, and the problem will solve itself.
