Indeed. I also think the writer's prose is poor - I think she was trying to write punchy copy, but doesn't have the skill to carry it off. For example: 'A weird but telling detail. Because it goes to the heart of why the story of Cambridge Analytica is one of the most profoundly unsettling of our time.'

Firstly I don't think either of above are proper sentences. Secondly use of 'one of the most' with 'profoundly unsettling' doesn't read well to me - for this to work wouldn't we have to commonly or often be in a state of being profoundly unsettled, thereby to have the collection that 'one of the most' seems to require?

These types of errors are strewn about the entire piece and diminish the authority of the writer.
