Your observation is brilliant.
In order to what you said, is that the social networks of the #bigtechs like Instagram, Twitter, Facebook, WhatsApp, etc., will never be a tool for the liberation of the peoples, of the opressed (us), as they structure social relations of domination and related to the interests of the oppressor. A tool creates a specific social relation.
It is pointless to open an account on twitter and shout "I will make the revolution from within!".
