Except that "Ubiquitous Language" is supposed to refer to terminology within a specific Bounded Context. In DDD it is desirable and expected that there is a mapping between them. This proposal tries to entirely erase Bounded Contexts. This is what I mean about people not understanding the words.

So in the sense of "what do we do about terminology not matching across an organisation" this and DDD are literal opposite solutions: one says "erase differences with a central definition (and bear the coordination costs)" while the other says "encourage differences with local definitions (and bear the mapping costs)".
