I was thinking about this some more, and now I think this entire conversation and vote is entirely irrelevant. Not just not worth having, but actually completely makes no difference.
A big company like Meta is gonna want to control what content is on it. Which means they're almost certainly not going to use a blacklist model, they're going to use a whitelist. This allows them to carefully control who they're federated with.
Their federation list will likely be a who's who of big influential mastodon servers, maybe some pixelfed servers. They probably don't even know that Lemmy exists, let alone the 8th largest instance. If/when they realize Lemmy is a thing in a few years, they might approach lemmy.world and/or lemm.ee.
All of this to say, I don't think this vote matters.
