Oversee and regulate in general, I'd go a step further and say once the private market discovers something like this we should have some part of the government develop a public alternative - that would solve a lot of the issues we're seeing with social media and companies like this by making them publicly owned and controlled
I think the big issue with deplatforming is that these companies generally have a monopoly in some way, so we need a viable alternative or they need to be publicly owned
