The offer is technically hostile because it was unsolicited, and the offer was made at the same time he indicated he wanted to buy-out the company (usually there's a gap). A more typical way of doing this would be to make a proposal directly to the board first. The fact that Elon did it in public means he's trying to pressure the board (via the shareholders) into taking an action they wouldn't otherwise want to take which makes it hostile.
