I don't know about garbage. While the oft-cited XMPP example is far from perfect, it'd be foolish to assume Zuck's intent isn't to acquire and monetize the majority of the Fediverse.

If I were him, I'd do it by co-opting the development, offering features like video hosting that the wider community would be unable to match. Certain Instances can be bought outright, others can be at least influenced with money.

This would serve to halt our growth, blocking the way forward for anyone to compete who could not match their resources.
