The document discusses how customer alienation and sabotage can negatively impact businesses. It defines alienated customers as those who have had a bad experience with a company and will negatively communicate about that experience to friends and family through both offline and online channels. This negative word-of-mouth communication, or "badvocacy", can result in lost customers and business for the company. The rise of the internet and social media has given alienated customers more power to widely share their negative experiences, and research shows that negative reviews online can significantly influence purchase decisions. Left unaddressed, customer alienation poses serious financial risks to businesses from lost revenue over time.
