Then you would still have private equity firms fucking everyone over, but with even less regulatory oversight.

I think publicly traded companies should be nationalized under an independent and thoroughly-audited oversight body accountable to the taxpayers, and any profits generated should be distributed to fund public works, social services, welfare benefits, and civil sector orgs.

And the idea of infinite growth needs to be abandoned entirely. These major internet companies need to be viewed as a public utility, and their goal should be to provide stable, reliable, quality services rather than churn an endless profit. This can only be done after nationalizing them though.
