The effect of a billion+ $ equity infusion (Musk) on Twitter general stock is what they were after. Now a lot of checks can get signed and a lot of servers fixed / bought and more censors hired. It costs money to run the railroad that has the 'brakes' on the information highway.
Musk just outed himself. Trump got another one to reveal the true colors, unless Trump and Musk are in on this for a strategy then, of course, that could be very interesting in that vein. Either way, Musk isn't doing this for the speech component 100%.
