I'm going to have to agree with the other reply. One hand doesn't know what the other is doing and the team that does audits to prop up revenue isn't going to care about that blog post unless it has legal language in the license that allows you to bypass licensing restrictions. That said, there's free versions of Oracle's databases for development and they may have exceptions for development purposes so if that's what someone is using containers for it might not be the end of the world.
