I think the routers can show if they were connected to the internet or not and if they sent out information over the internet.

Probably the biggest reason they wanted access is so they can say they thoroughly went through everything and every aspect of this.

To be honest I don't hold out much hope of anything happening really. I think a decertification is very unlikely :/ I would love to be wrong, but government will never move in a direction that stops their own corruption, so I don't expect this to be different.
