Facebook (fold it into Instagram)? Google (fold it into YouTube Shorts)? Elon Musk if he wants to lose even more money? Or any other very rich big tech company that wants to have an insanely addictive social media app? If nobody buys it then it will lose much of its value anyway by not being usable by a huge moneyed market which will apply downwards pressure on the price as buyers play chicken with each other. Plenty of buyers.
