Twitter in turmoil after month of crisis leads to concerns over leadership

Part-time chief Jack Dorsey's company is mired in high-profile hacks and concerns over leadership

A month of crisis at Twitter has reignited concerns that the company's part-time chief executive and years of accumulated technical debt" have left it dangerously vulnerable to malicious attackers and lacking the leadership required to take rapid action or controversial decisions.

In mid-July, Twitter suffered an unprecedented security breach as hackers seized control of the accounts of major public figures and corporations, including Joe Biden, Barack Obama, Elon Musk, Bill Gates and Jeff Bezos.
