"Arvind Narayanan, an assistant professor at Princeton University, is hopeful that Apple’s privacy stand will pressure other companies to follow suit. The popularity of Snapchat’s disappearing messages, and the occasional outcry when a company is caught doing something that looks unseemly, show that people do care about privacy, even if the tech industry provides few opportunities to express that, he says.
“People want to exercise these choices but they can only do it at certain moments, within the limitations of their time and technical ability,” says Narayanan. Pew Internet reported last year that 65 percent of Americans think it is “very important” to be in control of what information is collected about them."
