The recent tribulations of Facebook, which has lurched from crisis to crisis over the last year, most recently over the handling of users’ personal data, has pushed a few of the industry’s most prominent names to speak out against the company.

Marc Benioff, the chief executive of Salesforce.com, has compared the deleterious effects of social media to those of tobacco and alcohol, and has called for more regulation of those tech companies. Timothy D. Cook, Apple’s chief executive, has also suggested new regulation protecting personal data might be in order for businesses like Facebook.

“I think that this certain situation is so dire and has become so large that probably some well-crafted regulation is necessary,” Mr. Cook said recently at an event in China, referring to Facebook’s recent problems.

But don’t expect a long lineup of other industry leaders to speak out any time soon.

Although technology companies have their differences, a spirit of comity prevails among its leaders in moments of crisis. For example, technology chiefs have mostly kept quiet about Uber’s travails — from its efforts to sidestep law enforcement to a pedestrian death caused by one of its self-driving cars — even if they might express their opinions privately.
