I think they’re using “teaching” here in a way neither you nor I would. Because there’s no way they can put any lessons in front of the right students. That’s the algorithms decision. And those signs reek of astroturfing.

Where are you seeing that? Searching the article isn't showing that text.

I follow mainly therapists and pet behaviorists on TikTok so my take is the teaching thrives through regular user engagement. I can imagine a teacher letting students know they have a page and getting their start that way, too. It has its risks but it's really helped supplement my education.
