The picture implies a segregation way below the app/social media tier, into the space where the right-oriented xSPs (x = M, I, etc.) and large network providers of such orientation will no longer advertise their IP space outside their own routing areas, with maybe some exceptions for common/shared services (financials, gov, transportation, logistics, supply chains, etc., etc.), and also blackhole the left ones, and the other way around. The right-oriented networks could expand to include the to-be-new Russian IP space, maybe bringing along North Korea, Belarus and the likes. Firewalls could also be built, between right and left, where some [tightly controlled] traffic will be necessary. Interesting times ahead ...
