Oh good point. When you nest something into commas like that the sentence is supposed to still make sense when you remove the bit between the commas.
The irony being that now people use ellipses to mark a sentence pause, which isn’t really how an ellipsis is meant to be used. They were supposed to be for removing unnecessary but implied language from quotes. Agreed on the oxford comma though.
I agree that cybersecurity features should be included. In fact I think they should be included for free. The problem is that Microsoft wanted to charge the Department of Defense and it sounds like they used politics to make sure they could, and if true then they (and maybe also the DoD?) may have violated some federal laws around government procurement and “gifts” from contractors to the government.
