I think Musk just uses X as a world-wide propaganda machine now, rather than a cash cow.
He sacked 80% of the twitter employees, though.
Which might look like penny pinching, but as his declared aim, should Trump appoint him to the post he wants, is to abolish several federal (is that the right term for the departments above state level?), such as Education, and make huge cuts to the federal bureaucracy. So perhaps it was a trial run...
Cutting state bureaucracy has been a tory wet dream for a long time, one that they implemented in the name of 'austerity'. We live with the results and it's not good. But our cuts were nothing like what Musk apparently envisages. If he gets his way US citizens might find that cutting bureaucracy and 'red tape', though populist, makes life quite uncomfortable for them.
I wonder if he develops his own projects on a shoe string?
