Having memory problems doesnt make you copy/paste whole articles into your video scripts. It doesnt make you edit the wording to make it sound less natural and human to hide your plagiarism. It certainly doesnt make you do this literally dozens of times, over the course of years. It certainly doesnt make you less than the bare minimum of citing your work after your plagiarism is pointed out, and it doesn’t excuse lying about getting permission to use someones elses work.

Dude was ripping off dozens of better creators for years while making a mint, and now is just lying through his teeth as hard as possible.
