From the article, this is only in mobile users specifically. They both have ~150M mobile users. But twitter has about that number of "web" users, whereas threads.com/.net only have about 8.5M users. I can't find a link to the source in TFA, besides the similarweb homepage, nor can I find anything on their website about their methodology. Just two unsourced images on techcrunch of graphs from similarweb. I would really like to know how they are gathering this data.
