> If you are a tech company that becomes as successful as to be a monopoly or a participant in an oligopoly with a strong network effect, why wouldn't you be recognized as a gatekeeper?

Exactly. There are numerous monopolies that are scumming resources and wealth out of masses and not being tackled either because they’re owned by the right people or they’re strategically important. Then the discussion about how monopolies are bad and that’s why we’re addressing them becomes a mute argument. It’s supposed to be a government of the people, but sometimes it’s using it as an excuse to serve the interests of the few in right places, and not the successful companies.
