It's common in AI writing because it's common in human writing. Juxtaposition is a useful rhetorical flourish.

In general news paper article writers don't pick the title of their own article, it's someone else picking it for engagement (maybe using AI).

Also, FT is too big to not be aware of AI writing, and to not have internal checks (Pangram, ...)

AI speak infects human language now, people start to talk like LLMs.
