  • we are unable to continue to develop products for mobile devices that users find engaging, that work with a variety of mobile operating systems and networks, and that achieve a high level of market acceptance;
  • there are changes in user sentiment about the quality or usefulness of our products or concerns related to privacy and sharing, safety, security, or other factors;
  • we are unable to manage and prioritize information to ensure users are presented with content that is interesting, useful, and relevant to them;
  • there are adverse changes in our products that are mandated by legislation, regulatory authorities, or litigation, including settlements or consent decrees;
