Is it better for companies in the Fediverse to create their own instances, like is that how we’re likely to see the proliferation of corporations here? We’ll see a Pepsi instance, a FoxNews instance, a McDonald’s instance? I imagine that gives them the most control over what happens in their neck of the woods vs just having a single corporate account on like lemmy.world or beehaw or whatever (though I don’t entirely understand what having an instance entails).
Yeah, for any sizable organization running your own instance is the way to go, similarly to how you'd want your own DNS domain, email and web site. And just like with these other services your fedi presence could be hosted somewhere too but you want to be in control of it.
Makes more sense for The NY Times than for McDonalds. A commercial ad account would want to be found on a local feed of the biggest instance. The BBC experiment won’t work unless they commit to supporting it. Ideally, their reporters would have their own accounts, not just at the radio show level.
