Wonderful. What better way to drive home the message that the Russian government’s strategy of control over internet and Great Firewall makes total sense from the POV of national security.
How do those contribute to national security? "control over internet"/gfw aka censorship isn't going to prevent any cyberattacks.
Same as having a centralised firewall on a corporate ISP, having a firewall on a country level can prevent / monitor traffic to whole segments of IT infrastructure.
Currently a lot of the microelectronics is still manufactured in Asia but there has been a steady progress in acquiring capabilities to manufacture them within Russia. The costs are usually much higher due to much lower volumes, but since these mainly go to military and government infrastructure, cost is not a concern.
