Then the left should continue to build decentralized alternatives. Dual power is the only practical solution for when institutions are captured by reactionaries to suppress the left.
this has to include more than platforms for people to talk on - in a moment of crisis, no one involved is going to be posting on lemmy or mastodon, except to give public reports. real resilient communications infrastructure needs to be point to point, encrypted, and it must avoid normal internet infrastructure. if it touches a corporate router, it can and will be suppressed by the state in the name of crushing the left.
moreover, dual power must include mutual aid and mutual defense if it’s to actually live up to the name. platforms to talk online with comrades are nice and all but it doesn’t on it’s own build any kind of base of power.
