The first quote is an great demonstration of using logical fallacies to sell a point, and I am glad the article breaks down the argument. Anyone using a loaded question such as:

Is the goal of the Fediverse to be anti-corporate/anti-commercial, or to be pro-openness?

Doesn't fundamentally understand the fediverse. Almost every projects goal is supporting the decentralization of these technologies. To quote the website fediverse.to:

The fediverse is a collection of community-owned, ad-free, decentralised, and privacy-centric social networks.

Allowing a single entity with a larger and more dominate platform, more power in the legislatures of the world, and effectively infinite times more capital to come in destroys the decentralized nature. Meta also doesn't stand for "community-owned", "ad-free", nor "privacy-centric". Meta's goal here is pretty obviously to centralize and control the networks as much as possible, and scrap the remaining data from other instances, using the ActivityPub protocol. Meta is a corporation who's motives are to increase shareholder value. The fact these are community ran instances is like Walmart coming in to stomp out the local grocery.
