I said the tweet reads “like someone who”. I wasn’t being definitive because I know I could be wrong, but the manner of the tweet came across like they weren’t fans of the artist before and that’s what I interpreted from it when I first read it.
Then I had a look at their other tweets, and they mention working on a music site when FKA twigs first came to prominence, and if I recall correctly the tweet implied they didn’t care for LP1 and thought it was overrated.
Edit: Also they’ll probably have heard bits of the singles/videos going in and known what to expect. Which again added to my interpretation of the tweet.
