Well, I guess they are buying the insurance from me then; I still don't buy the short insurance argument entirely - the math may make sense when the strike prices are only fractions of the underlying stock (i.e. RDFN is at 17 and offers strikes at $1 intervals, so the next price up is just 5% above current stock price - not sure that it makes sense when the next strike price up ($5) is 45% above.
