It should be pointed out that the author of this article had a private meeting with Meta regarding Threads and signed a NDA. He is also the head of a company that receives funding based on the popularity of the Mastodon software. There may or may not be deals we don't know about, but he is certainly not an unbiased party.

Meta's business is monitoring and using online social networks to manipulate human behavior. Their massive userbase will cause Threads content and users to dominate instances that federate with them. It's more than just "no like".

I am completely in favor of defederating from Threads. My personal bias against Zuck and his monsters aside, there's the very real chance that he'll use ActivityPub as free content for his own product's growth, slowly adding changes to the protocol until the "best experience" is only via threads

There is precedent in the form of Google and XMPP. In another thread, someone argued in favor of Meta and replied to that what happened was simply "Google outcompeted XMPP by offering a better user experience", not realizing that his argument was actually evidence against Meta. Google beat the competition. Thinking Meta will work to beat the competition (ActivityPub) is plausible.

Remember when Facebook wanted to buy Snapchat, but Snap refused? Facebook then added the stories feature to FB, Insta and Whatsapp (the latter 2 apps bought in order to further consolidate its power), in order to bleed Snapchat's userbase.

We can't predict the future, but Facebook Meta's past actions all point to a very likely chain of actions (Embrace, extend and extinguish).
