Imagine buying a car that says, "Save $5000 for a less safe version without airbags." Yes, I know Airbags are DOT requirement, just trying to make a point.
Edit: I think people are missing my point. I am not saying they don't sell cheaper models that are less safe. My point is that they don't ACTIVELY market them as such. Point me to an advertisement that says "Save $5000 for a less safe car!". This is in the spirit of what the GP was talking about whether cloud providers can market as "Less secure but cheaper HT option".
