If this kills Twitter, I think Musk will be annoyed but it's still a net success for him.
Next time Democrats are in control he may be looking at an antitrust lawsuit.
The rule of law looks pretty ineffectual at that level. Only one of the various trials against Donald Trump got a verdict in the 4 years that he was out of office. Everything else ran out the clock and at this point is dead in the water.
That dog has no teeth anymore, and it likely won't in better health after Trump's people restructure the FTC and the Justice Department - considering Trump and Musk's respective run-ins with financial regulations I think it's safe to say those won't be stronger in 2028.
Heck, even the S&P 500 has already taken back all the gains from the post-election spaz. I don't think the economic prospects for Elon or anyone else look assured at this point.
I sense an ego clash coming regardless.
