After seeing how the telecom infrastructure was targeted in Ukraine, No sane government in the world can afford to maintain an oligopoly telecom infrastructure anymore; Ironically often in the name of national security.

I think the best way to address it is to open the industry for disruption by encouraging new players(without Billion dollars in market cap) by removing barriers for entry, With stringent monitoring/punishments for anti-competitive behavior including backroom deals among carriers and mobile ecosystem duopoly.
