Actually effective strategies against #Meta to prevent an #EmbraceExtendExtinguish are difficult, but they start from asking "what will actually help here."
I maintain that preemptive #DefederateMeta is ineffective for this and that defederating from those who won't defederate from meta does more harm than good.
But what will help is thinking about the roadmap and getting there first. What will help is building a robust and thriving community around #ActivityPub and other fediverse protocols.
Meta is looking to implement post importing. That's been a feature request since forever (see https://github.com/mastodon/mastodon/issues/177 and https://github.com/mastodon/mastodon/issues/12423 ).
Secure messaging is another example.
These are things that if meta implements them and does even a halfway decent job then #meta controls the standard.
Want to prevent that?
Get there first or at least have a strong offering on how to do these things out of the gate. Let _us_ as a community control the standards that we use.
