I'd be more okay with these people phoning it in with their research if they actually credited their sources properly, most either don't at all or barely do it.

Also this isn't someone slacking at a corporate job, they're making pretty damn good money by fostering a parasocial relationship with their fans. Some are even successful enough at it they can springboard it into starting their own small business ventures meaning they're basically kulaks. And often when someone points out that their work is copy+pasted from somewhere else they sick their fandoms on them, or sometimes even get the people they copied from harassed.
