I found it strange as well that the article cited an unrelated study for notetaking. Also, I didn't know Canvas could be self-hosted like that. That's neat. I hope more schools take the time to do that, even if the chance is pretty remote.

I imagine it’s not easy to self-host. I certainly won’t pretend the company is making it easy to do so.

But it also seems like one of the most popular options (moodle) is OSS and typically self-hosted.

So if it was me and I was writing this article I’d be addressing it at educational institutions and the way they use LMS. Because there’s just no way you’re going to convince anyone to stop using them.
