It's worth noting that all of this drama stems from the (somewhat opaque, to put it nicely) reddit comments of one KDE developer, so that warrants treating it as a rumor in my book.

It would be prudent to wait for an announcement or clarification from KDE leadership before assuming anything one way or the other.

The Reddit thread had comments of 2 KDE developers and a link to the merged merge request removing FreeBSD support.
