Well, maybe, except there's a few problems with that;
- Buying Twitter is a bit different to buying a house. The offer price for shares is set, and (as far as I know) Elon can't move it without withdrawing and reoffering, which incurs all sorts of fun legal issues and penalties.
- If it's due diligence and Elon actually might withdraw from the deal then fair enough, but then it's not a bluff.
- If it's a bluff, and Elon still intends to buy, telling the world there are actually more spam/bots than the Twitter reported devalues the company. It doesn't seem like a great move as an investor.
