For anyone else coming along reading this thread, in searching for Brexit's impact, I see mention that while a sharp recession and many of the doom-and-gloom style predictions didn't happen, it _absolutely_ has had a negative impact on the economy, and that it's expected that the effects are long-term and will continue.
I do think it's potentially fair to say that some of those effects aren't relevant for this particular article or discussion, due to the recency. The movement around it didn't arise out of nothing, after all.
