The problem is that we have allowed them to be benevolent monopolies and now that they control practically the entire market in their respective spaces they are not so benevolent any more. Nobody cared to choose a different search engine because google just worked, nobody bought things from a different website because amazon was fast and had everything. Now google search is just a way to sell me an ad for the thing I’m looking for and Amazon is just a way to sell me an ad for the chinese manufacturer who paid them off to push their results to the top or in some cases it’s their own competing product.
