Those of you not plugged into the Mastodon community may not be aware of the predominant reaction to Instagram Threads. This started when it was merely rumored, reaching a crescendo with reports that Meta had been talking to a few of the larger Mastodon instances under NDA, presumably to encourage them not to “defederate” with Threads when it came online.1 Let me describe that reaction for you, with only mild exaggeration:
I’m merely describing the actual real physical changes that Facebook causes, on purpose. Every single click you make on Facebook makes you a worse human being.
Those people are still welcome to join here. They just shouldn’t be permitted to do it through a server known to be malicious. Facebook is malware and letting it connect to your server makes your server just as dangerous.
Monopolies don’t just exist when you literally only have one choice. Having 90% of the market in and of itself is an extremely powerful position. It happens all the time to decentralized systems.
