There's more context in another HN thread: https://news.ycombinator.com/item?id=47602859
As an outsider it's pretty opaque to me. I think the Document Foundation (handling LibreOffice) wanted to (re)release an online office suite that seems to compete with Collabora, which sells one. But the biggest contributors to LibreOffice are Collabora employees. I thought maybe they feared Collabora taking over the org, but it looks like there are formal legal disputes between the two, I think (see the post from the LibreOffice side https://blog.documentfoundation.org/blog/2026/04/01/comment-...).
And of course when legal issues are involved everyone is being very vague. I just hope it doesn't hurt LibreOffice's development too badly.
