I heard Facebook was going to make something "built on Mastodon," but I didn't think federation was on the table too. I would think a company wouldn't want open federation, that sounds like a content moderation nightmare.

Likewise, if I ran a Mastodon server, I'd block them immediately. I don't use Facebook for a reason, and anyone who would just blindly let Facebook scoop up their community data is part of the problem.

I posted this on Mastodon, but I completely disagree with the idea of defederating from Meta instances on principal for the same reason I don't want my Fastmail account to stop interacting with Gmail accounts just because I feel Google is too corporate. That defeats the entire purpose of open standards and federated content. I should be able to choose to personally block content from Meta instances if I want to, but it's to the detriment of the community to fracture the Fediverse just because it's starting to grow large enough to attract attention from one of the big tech companies.

The reality is, a federated Meta service would at least initially grow the idea of federated social media as a whole, and likely drive traffic to Kbin/Lemmy/Mastodon from people who want to get off of the Meta platforms, but don't want to cut contact with their friends/coworkers/enemies entirely. While I probably wouldn't make an account, I'd be interested in at least being able to follow a few of my friends who I actually have interest in seeing updates from via my Masto/Kbin accounts.

And I'm aware of the embrace/extend/extinguish paradigm, but premature defederation isn't the answer there either.

I'm an advocate for federated content for convenience, not on principal alone.
