We don't consider Google's ad network software to be malicious, so we don't warn our users about the presence of AdMob and MoPub, but we do provide some of this information under Privacy Advisor.
However, most of the AD frameworks related to the articles you have posted will be detected asap.
AD Frameworks that display any kind of advertisements outside of the scope of the host application should be considered as PUP. If they perform additionally malicious actions they could be also considered as TRJ.
