He has indicated that he'll fire most of the employees[1]. In practice, I think he'll move the talent pool whose job is to optimize ad delivery at Twitter to Tesla/SpaceX/OpenAI etc... and make Twitter paid for by the users, not by the advertisers [2].

Your logic seems to be that if someone imagines a crime occurring that they've actually committed that crime?
In forums like this, when it comes to new things, people are trying to make sense of what is happening by sharing their opinions and what they are basing them on... in hopes of getting either supporting or opposing views and letting that collective opinion sharing guide themselves and others into what might really be happening. We're not defending out scientific paper nor are we building up fake authority to scam people.
I feel like there are only so many moonshots you can pull off before you get a Waterloo as you said.
Taking on Twitter will not only be a huge amount of work, it is likely consume a ridiculous amount of talent -- which could be focused instead on building next-generation humanoid robots, electric vehicles, energy solutions, reusable spaceships, and space stations.
Musk has a long history of taking on more than it's humanly possible, but so far he has been narrowly avoided failure. Recall that Tesla was ready to file for bankruptcy at one point in 2019.[a]
He hasn't sold any shares, so he's likely borrowing against his Tesla stock to finance this hostile takeover, exposing himself to all sorts of potentially ugly debt squeezes.
I really, really, really hope Twitter doesn't become a black hole that sucks talent and energy away from more important things. More than that, I hope this latest battle doesn't become Musk's Waterloo.
