It’s a joke (from the author of the article and not a quote from Zuckerberg). Usually in the format of “xyz will continue until morale improves”, where xyz is something that is likely to reduce morale, thus implying that xyz will continue indefinitely.

An alternate worded headline would be: “AI content will continue on Facebook regardless of whether users like it”.
The Glimpse Editor project shut down because there weren’t enough contributors, and the founder didn’t have enough time to do everything.

…and yeah it wasn’t just a rename, their github readme suggests they were making UX, accessibility, settings, and plugin changes to make it “enterprise ready” (not sure on the specific details of that though).
