Re: Can anyone bother to explain
It's unreasonable because they're completely disingenuous. This isn't to protect sensitive systems from outside intrusion; if they're afraid about those, they'll have airgapped some and built special networks for the rest already. That's what you do if you don't want people to get into your systems--you disconnect *those* systems. This is so they can, at will, cut off access from general citizens to specific sites (all through the runet firewall) or everything if they're feeling paranoid. Essentially, they looked at China and said "if only we had been in power when things were being set up, we'd have a system like that. Let's try to build one now.", then emitted some garbage about how the terrible hackers need to be blocked from Russian network activity.
