Clarence Page: Elon Musk makes his move on Twitter — but toward what?

First he said he would, then he didn’t.

Less than a week after the announcement that Tesla CEO Elon Musk had become Twitter’s largest shareholder and would be joining the company’s board, Twitter announced over the weekend that, well, not quite.

Musk, the world’s richest man, remains the largest shareholder of Twitter after purchasing 9.2% of the social media giant’s stock, but he won’t be, Twitter CEO Parag Agrawal announced Sunday. No explanation was offered for the reversal.
