Or, following Ockham's Razor, it would indicate he needs money to do something with it.
Maybe buy $600 million yacht or maybe buy money losing company.
He bought ~9% of Twitter already. I'm sure his co-shareholders prefer that he takes control over companies he bought in, because he can then easily develop synergies (cf. Boring Co and Tesla, SpaceX and Tesla, SolarCity and Tesla, etc).
The problem with this idea is that nobody's really on Twitter for the free speech. He might take the company to new and exciting places, but it won't be with the current userbase.
