A new survey of 1,000 American Facebook users by technology research group Techpinions found that 9% had deleted their account completely due to increased privacy concerns that have come to light amid the Cambridge Analytica scandal.

Seventeen percent of the respondents say they’ve deleted Facebook from their phone and 11% say they’ve taken it off of other devices.

“Fifteen perrcent of our panelists said there is nothing Facebook can do to regain trust as they are just ready to move on to something else,” wrote Carolina Milanesi, principal analyst at market intelligence firm Creative Strategies, who worked on the survey with Techpinions. “Of course, if this sentiment were to be similar across other countries, 15% of 2 billion users is a sizable chunk of the installed base that would disappear. What is interesting is that the number grows to 18% among people who are said to be very aware of the Cambridge Analytica incident.”

Other key findings from the study include:

• 28% of the people surveyed said they never trusted Facebook to begin with.
• 35% said they will be using it less than they used to.
• 31% changed their settings.
• 59% said they would not be interested in a paid Facebook product without advertising and with stricter privacy protection guarantees.
