If I am running a CRUD app for some business domain, does its value derive "substantially" from the functionality of the underlying database? Could a lawyer argue that because one of Slack's major selling points is the speed with which messages are delivered, its value derives "substantially" from whatever technology they use to enable pub-sub? Even if Redis Labs wouldn't be so aggressive against Slack, could we count on that if they were acquired by Oracle, or if their acquirer were acquired by Oracle? In such a case, Slack would be in a pickle - they might be liable for having used the software without a license historically, which is in many ways a worse situation vs. having had to negotiate a commercial license in the first place. It's an insidious gotcha term wearing the cloak of open source, and thus it tarnishes the brand of the entire open source community.
