The interesting here is: What is a product? Most open source is not. The millions of libraries are not products. A product accumulates the various aspects (cybersecurity, license, ....) into a package. If I buy the software from a vendor I will make him responsible for it. If I hack it together on my self, this duty is on me.
Open Source will survive that. But open source owners will get tons of questions and should be better be prepared to answer questions. GitLab and GitHub are already working on the consumer side with their security analysis features.
