Google reportedly exposed the personal data of about 500,000 users of the Google+ platform.  Potential misuse of personal data by outside or third-party developers may have existed for years due to a bug.  Adding insult to injury Google decided to conceal the error to avoid the consequences, according to the Wall Street Journal.

The parent company of Google, Alphabet, responded by announcing that it would shut down the Google+ platform and operations.  Known to many as G+ and launched in 2011 as a social media competitor to Facebook.  The project was never embraced by social media users and has been mostly defunct for years.   Shares of Alphabet fell roughly 1 percent in response to the story and the closure of G+.

"Our Privacy & Data Protection Office reviewed this issue, looking at the type of data involved, whether we could accurately identify the users to inform, whether there was any evidence of misuse, and whether there were any actions a developer or user could take in response," Google said of the error in a statement to VOA News. "None of these thresholds were met in this instance."
