Found this post super informative as it relates to Mastodon, and thought Lemmy might also benefit from this perspective. I'm not sure I share his optimism, but his points seem sound to dampen some of the alarm bells over Meta joining the Fediverse.

I'm not sure about Mastodon, but at least for Lemmy, not every piece of information is available from the API or web interface. Some of it is only sent through federation. Namely, who, specifically, voted for something, edit history, probably a few other things.

Does Mastodon just hand over a complete list of everyone who liked a post? Even if it has thousands of likes? That kind of data would be very valuable to a company like Facebook.
