This is Jay, the CEO of Confluent. No, actually quite the opposite. We took pains to ensure that the license was written so that software products like Landoop were free to embed our open source and compete with us in that way. This FAQ covers the competition in more detail: https://www.confluent.io/confluent-community-license-faq
I am no expert on this, but based on Bryan's analysis, if Landoop were to release a SAAS offering of their product, they would be in breach of the license. As Landoop are pushing Kafka on Kubernetes, I assume that is their strategy - to have a SAAS offering at some stage (we are all going to the cloud, i thought?).
