What about we have more people like you, like me, like us that get away from big shitty corpo like Reddit and move to Fedi in mass? That's how a real free market works: if you don't like it, you leave/boycott.

The same principle applies to any aspect of society based on the market. The real 'ambition of the powerful' is usually fueled by State granted monopolies and regulatory capture where big corps use the law to kill small competitors.

Limiting their power shouldn't mean giving the State more control (which they eventually buy anyway), but rather decentralizing our choices. If we have the freedom to exit and build alternatives, their 'power' evaporates because it lacks our voluntary consent.
