One viable alternative is legislation, such as the EU has been doing to some effect. Of course the laws lag the technology by some years and we have a wide range of political views on things like "the right to be forgotten" but more consumer protections seem to be needed, perhaps also factoring in "dumb" consumer behaviour e.g. not reading Terms & Conditions.
Some things are impossible to solve by independant actors. Imagine trying to boycott cars in the 1940s because they were manifestly unsafe, or in the 1950s because they polluted the world with lead.
Only legislation changed these things... albeit not enough. Same for workplace safety, child labour, and so on.
Some systemic problems require systemic solutions.
