While I personally disagree that Stars and Stripes should be shut down, the complaint that Stars and Stripes is all we had is just

in this day an age.
I am very familiar with multiple military bases of major importance and they are almost overwhelmed with individual consumer level Internet connections via both landline and cellular. To the point that it's a legitimate national security concern. I can think of one military base in particular that literally has hundreds of Internet connections that have zero cyber-security overlay on it, unless the individual user or civilian contractor is doing it themselves. Because IT security is not being provided by the military itself on those connections. In many offices they have the mil.net side and open consumer grade Internet accessible in the same facilities. Hopefully it's all being run through a firewall.
All that said, S&S at least needs to stay online.
