The illusion of infinite growth on "free use" ad based business dies when investment funds demand more benefits from former startups now turned into corporations whose only asset of value is the their users' data. You are the product, so it's time to squeeze you.

I think such data is currently overvalued on a overgrown ad-targeting market with too many competitors, and adding more ads only devaluates each ad value further, because users' consuming capacity also has a limit. So I see a severe correction coming. Another bubble burst, and another crisis inside the crisis that late capitalism itself is.
