Extinguish: When extensions become a de facto standard because of their dominant market share, they marginalize competitors who are unable to support the new extensions.
By that logic Lemmy/Mastodon/fediverse are already extinguished. Those of us in the fediverse are already "marginalized" wrt Twitter/Threads/Facebook/whatever.
There are very good reasons to hate Meta, but personally, I think EEE isn't the biggest issue.
