I have domains that have deliberate broken DNSSEC. Does that that count toward DNSSEC being broken? Same for TLS, I have websites with broken certs.
If you want to say something about how the internet is broken, then look at production traffic. Don't just take the list of all .com domains. Because many of them will never see any traffic.
Of course, nobody is going to report on the alexa 1 million. Because that would be completely boring.
