There is no flavor of free where reliability can drop to zero and still be attractive. People may lie to you - and themselves - about it being okay but once they get a taste for it they’ll keep trying to renegotiate for a little bit more.<p>If you come at this class of problems saying we are going to take a very small amount of resources, I think you’ll have better outcomes.

At least you’re being upfront about it.
