The damage is corporations could now determine whether they classify downstream use of open source code as "valuable" or "not valuable", and determine (according to their own rubrics) whether to effectively end the open source gravy train in their own ecosystem, or be a member of the open source community and share alike.
Despite every attempt by Red Hat employees to call out CentOS Stream as being "Red Hat sources", it is not. If they wish to participate in the open source ecosystem, they can't coerce customers (paid or not) into a particular (very proprietary) usage pattern with their software. No matter how many tens/hundreds/thousands of employees they hire to code for open source projects.
