DETROIT (AP) — Elon Musk has put his plan to buy Twitter on temporary hold, raising fresh doubts about whether he’ll proceed with the $44 billion acquisition. In a tweet early Friday, the Tesla billionaire said he’s skeptical that the number of inauthentic accounts presented by Twitter is as low as the company suggests. The issue of fake accounts on Twitter is not secret. In its quarterly filing with the SEC, even Twitter expressed doubts that its count of bot accounts was correct, conceding that the estimate may be low.
