F-32?

I dont claim to know anything about US Laws and military contracts, so heres my question:
When Boeing lost the JSF program, was the F-35 better in all areas?
If not what is to stop Boeing trying to sell their a/c abroad?
Its ugly I agree, but , for example, it was better at the Stovl role, why cant they sell that version while the f-35 gets then other orders?

I think our forces deserve to the best possible equipment available.
