Do I believe that giant corporations (like Google) will attempt to compromise the Fediverse?
Sure, I have an almost certain expectation that they'll try.
But the other side of the coin: when they try to compromise the Fediverse, we compromise them!
For example, if they start an instance, that means they're compromising their walled gardens.
Good ☺️
The thing about being practical and relentless: each time Silicon Valley deviates from de-centralization, we need to change the terms.
They're creating accounts on the Fediverse? Okay, make the conditions such that they must host an instance.
Now they're hosting their own instance? Defederate if they're disrespectful of community norms.
They're blocking big volunteer-run instances for skeezy reasons? Start small single-user instances.
