Is it that you don't believe these pieces of malware are generating fake engagement on Google's properties? Or that Clicks, Views & Users don't matter to Google?

The extensions engage in affiliate fraud (ie. injecting affiliate code/cookies to links/sessions) and collect user data. That hardly counts as "engagement on Google's properties", which are mostly search ads and youtube. To my knowledge google doesn't have an affiliate network, so they're not getting anything there either.
You seem to imply that the extensions are engaging in ad fraud (eg. viewing/clicking on ads), but there's no evidence of that presented in the OP or in this comment section.
