You've just shifted the goalposts significantly and did not really reply in good faith. Showing ads is very different from linking to malware. Especially on YouTube the amount of malware is probably very low since everything is sandboxed.
I think the point is that putting so many ads on a page to the point of it becoming indistinguishable from a malware infested shit site is a form of abuse to the user. I personally agree with this take, if that's what he meant
Showing ads without properly vetting them nor taking responsibility for any malicious ads is not in good faith either.
