As someone working at a bigtech co that has spent every single working day (and many weekends) since the launch of Mythos patching serious, company-ending type of security issues, these types of posts really irk me.
Public datasets of CVEs being underwhelming doesn't mean much if all of the issues are in private company codebases that will never get a CVE number assigned and will never get a fancy blog post. You're never going to hear about them, and the people working on them probably can't tell you about them, but that doesn't mean they don't exist.
We're all worried about OSS having security issues because of how widely used things like PHP or curl are... but the same can be said about email providers, document collaboration SaaSes, payment processors, etc that millions of companies depend. Those companies will never be in datasets like this, and they'll never publicly disclose how many issues they found.
