societal ostracization (e.g. boycotts)
sabotaging data centers, data gathering infra (flock cameras), web infrastructure
These are just methods within the current societal norms and context, if not I could think of 10 more.
For example, it is not beyond the realm of imagination to think that large swathes of people could stop using technology (as in phones & computers) altogether, and return to a more traditional physical communal state.
It is not beyond the realm of imagination that countries, after suffering from cyber attacks, could start decoupling themselves from the global internet, and wall themselves off (similar to China), and develop their own unique culture around technology.
It is not beyond the realm of imagination that tags like Anti-AI be mandated to be attached to products similarly to kosher, halal, etc.
