The reference is to a previous licensing change, which made it less free, with Oracle shaking down groups using the Oracle JDK. They've changed their terms before and could do so again with future releases.
Like making it even more free? You are literally free to use the “paid” OracleJDK on its latest LTS release up until the next LTS comes around+1 year.
