Code.org is not "pushing for pay deductions on teachers whose CS classrooms consist of <40% females" as you claimed.
The actual proposal: [1]
* isn't about teacher's pay, its about classroom funding rewards being paid by Code.org [2]
* doesn't refer to % of class that is girls, it pays $750 if 15 or more students reach a certain goals, and $1,000 if, of those 15 or more, 7 or more are girls.

[2] Direct quote: "These rewards are not cash prizes for teachers - they are classroom rewards. This program is not permanent, it's a one-time campaign to see if rewards can help grow the pool of C.S. teachers and increase total enrollment (especially by girls)."
