Elon Musk’s rejection of Twitter board seat could signal major move

The decision by billionaire tech entrepreneur Elon Musk not to join Twitter's board after buying a 9% stake in the company gives him the freedom to buy an even larger share of the social-media giant.

When Musk became Twitter's largest shareholder, he signed an agreement stipulating that as long as he served on the board, he could own no more than 14.9% of the company's stock, pointed out journalist Yashar Ali.
