Customers will pay for Docker Hub potentially. The type of customer who would pay them for Docker Hub is roughly the type of customer who would pay for Github (with market size constrained by Docker adoption.) That is, customers who are willing to pay a bit for private hosting of some part of their development or deployment process and are willing to do that using SaaS. My tiny company pays them for private repositories as part of our deployment process. (Push to Github, Docker Hub makes automated build, built Docker image gets sent to AWS ElasticBeanstalk). It's worth the $7 a month for the convenience of not doing the builds and hosting the images ourselves. Not saying it's going to turn into a business model that will justify that valuation, just that it does at minimum provide a value I'm willing to pay a small amount for.
