How?
Certainly not for the investor.
It does seem to be his stated goal.
Vulture capitalism for those not familiar (it has been a few decades since it was popular) is a term used to describe a thing where some firm will come in, buy a business, gut it for anything valuable (leases, buildings, stock, employees, machines) and leave the rest to wither and die. The idea being some company might own more in materials than the ostensible value of the company according to the stock market and thus you come in, sell off all their materials at market rates (or possibly use them instead of buying it yourself, which is probably closer to what this is aiming for), net a tidy profit and run away to do it again. In this case his stated goal was he things Twitter's underlying technology (and possibly user base) means he can leapfrog a few years of development time for his everything application (time is money and all that, even more so if someone gets the jump on you and builds it before you). I don't get it myself for the technical side (technology at scale does mean real problems get solved over the simplistic thing that any programmer could knock together something that works for a few hundred people for in an afternoon), and the user base was very small actually compared to most other companies working in the same space (
https://backlinko.com/social-media-users covers various things, Twitter is and has long been lower on the list than many others with its growth having stalled somewhat in recent years as well) nor composed of particularly high quality users (you don't care about some poor kid in India where some trust fund kiddy in the Los Angeles hills you value rather higher on the monetisation side of things. Likewise I can't imagine the inane witterings of a few so called journalists and acting/singing unit 3073 are a particular draw as much as both of those classes would like to think it is).
Anyway as for the matter at hand so you (in this case you being a fairly rich man that got stupidly rich courtesy of ridiculously hype in your car company) buy a company that has no users, much less crazy valuable ones, that is existing purely on the whims of venture capital, loans and handouts from those that care to pay you to attempt to control the narrative/discourse as befits their whims, is full of pampered useless people (I am sure we all saw the day in the life of the tech professional non tech worker videos (
quite like this series if you do want a catch up, can't remember if that was a twitter one but it is all much of a muchness for tech companies like this) at best and corrupt as you like at worst, all for too much money even by the standards of the overinflated stock price during an economic downturn everybody and their dog saw coming. In an attempt to stem the bleeding you take a scythe to management (whether a company is downstream of management or upstream of employees is a debate you can have), the fluff (see previous linked videos) and things potentially bottlenecking your growth potential (overly censorious types on your platform that is ostensibly about speaking to people), try to undo some of the damage of some of the previous lot, take a somewhat derided policy and instead turn it into a money earner (possibly a bit premature or heavy handed if you instead do probably want to coddle some people and make them feel they are special, though pain now for better outcome is a possibility).
In the end if it becomes a free speech platform then we win, if it remains the same and just idles doing not a lot while being containment for useless people then we win, and if it implodes possibly taking him down with it (I would probably view him more favourably than most of the billionaire set but that is not a high barrier to pass, and I do still remember hyperloop and the hot air that is Tesla) then we win. From where I sit makes more sense than buying a newspaper as a vanity project would in current space year (nobody reads/trusts/cares about newspapers any more, buying one then being even more of a waste of money). In the end nothing of value gets lost.
