This is the right answer.

Collecting profile pics, posts, likes, and so on, is basically what is needed to federate. If they don't collect that, they can't display things from other instances.
And guess what our instances will collect the same data from Threads to be able to display stuff from there...

If you're already using Wordpress, there's an ActivityPub plugin, it's semi-offficial, and this close to becoming official.
i.e. it was developed independently, but Automattic bought the plugin and hired the developer. Apparently, it'll eventually be integrated into Wordpress (probably through Jetpack - my assumption).

I use it, it basically allows people to follow your Wordpress blog through any Fediverse account, just like any other Fediverse account. You can decide if the full post gets pushed in followers feed, or just an excerpt, or just a link, etc, a bit like RSS.

They have started moving to paper bags in some of the newer sets, I believe). Not to mention the CMF being now in cardboard boxes, but that's going to be a disaster.

Je pense effectivement que ce sont les raisons.

Meta a 2-3 milliards d'utilisateurs. Le Fediverse en a pas plus de 10 millions...

The Roanoke colony is not a really fitting comparison (actually there are none, this is literally unprecedented), they were still on Earth. And they vanished because they had no food. And they didn't vanish into the void. They were welcomed by a native colony nearby. Most integrated into the colony, some traveled to other places, died, or were integrated into other native villages.

If a Mars colony runs out of food, I'm not sure there is a Martian village to welcome them.
