I think you’re being a bit too generous. Despite the fact that this particular video was pretty good overall (though the potshot at environmental activists at the end was wholly unnecessary and the opposite of helpful) I didn’t hear any real admission that her past views were mistaken here. If what you say is true, then she needed to own up to that far more clearly than she did.
Although I have only watched a few of her videos in the past before stopping. I found them quite opinionated and misinformed. So I don’t have the full context of what exactly she got wrong previously.
