I'm fine with the government claiming a state secrets privilege and the judge upholding it based on an in camera review. However, I see no reason for the case not to go forward with the available evidence publicly presented. This is a reasonable check on the government use of the privilege. If the government wants to hold back evidence, then the case gets decided on the available evidence presented to the fact-finder.
