Customers are exploring Salesforce Communities for many use cases because of the no code/low code community builder capabilities which enables speed to market and ease of administration. When looking into the AppExchange options specifically for Communities for secure file sharing, onboarding, collaboration, etc that could easily be plugged in, the Box Communities Lightning Component Pack is quickly ruled it out because of the lack of capabilities and the fact that it hasn't been updated since 2016. Most Salesforce customers are either already using Communities or are exploring Communities as a fast, no code/low code option to connect with customers, partners, and employees.  To go along with this, they are looking for easy plug and play options from the AppExchange to extend the capabilities of Salesforce Communities to meet certain needs/use cases.  In the area of file sharing and collaboration, Box would stand out as a secure and easy solution if the community lightning components were more updated and on par with where Box is at today with capabilities.
