Organize and signal-boost the mob that wants to persecute you, ban and deplatform anybody who dares to defend you, promote any material saying bad things about you, suppress any material that says good things about you. You don't live in a vacuum, neither does your employer, neither do your employer's clients, neither does your family, neither does their employer, neither do teachers at the school you kids go to... etc. etc. You get the idea. You don't have to be a member of the platform for it to be used to attack you.
I think the argument is that, should Facebook use become pervasive enough that the bulk of interaction, be it social or financial happens there, you have already disappeared by nature of not using it.
Facebook, willingly or not, is part of the same entities' sourcing and influencing activities. We know this as established fact. Both your side's and various multipolar others.
