Once upon a time, the browser wars revolved around which browser supports more or better extensions. As those extensions became more popular or got imitated, their exclusivity became less of a selling feature. In fact, extensions themselves have become somewhat of a liability because of security and privacy concerns. Unsurprisingly, Google's Chrome Web Store has become a haven for those kinds of unhelpful and even harmful extensions. Given the times, Google is putting in place stricter rules to reduce the number of spam and misbehaving extensions on Chrome.
