The big issue is that the companies have absolute power over facilities that should be mankind's possession and thus managed with explicit laws and a justice-like system offering due process. Google is managing mankind's search engine with a secret algorithm and they can arbitrarily decide your site's presence or position in search queries with no recourse (granted, it's hard to define a fair way to do this, but still). Facebook is managing mankind's person-to-person communication system and you have no recourse if you are banned, if your content is removed, or if you are trying to publicize some content and the newsfeed algorithms are unfavorable to you. Amazon is managing mankind's delivery system and you have no recourse if they refuse to carry your products. [Apple is less of a problem because they are merely monopolizing iOS devices, and there's an easy fix in terms of forcing them to open source iOS and license any related patents, so that iOS apps can be made to run on Android devices] Reddit is another huge problem as they manage (and especially allow random moderators to manage) mankind's discussion forums with no regard to free speech, with arbitrary bans and no enforced transparency. One option is to enforce competition: this could be done for Google by only allowing them to operate their search engine for up to a few consecutive hours per day, can be done for Amazon by allowing them to operate only a few days per month, for Facebook by forcing them to federate their social graph, so that people can host their accounts on any service and still have the same interaction and for Reddit to also federate their forums like Usenet is federated. The other option is to be force them to manage all these facilities in the public interest, with explicit and published rules of operation (e.g. Google and Facebook must publish their ranking algorithms) and with all protections like free speech applying, according to well-defined rules and providing due process for any decisions that are adverse to anyone. Obviously these should be as much as possible be general laws, like extending free speech to apply private spaces as well, forcing to put any software that can generate lock-in (e.g. because it implements a proprietary widely used API or manages a proprietary widely used file format) in the public domain and forcing to federate any service that benefits from network effects.
