Nothing to disagree with here. Come to think of it I hope COVID puts more recorded lecture online from Ivy League et al, overall. The only issue is that it's easy to put them behind paywall or student logins or what have you. One bonus with the Google/Facebook/whatever approach is that you sometimes get academics who became in-house researchers to teach their courses. This was more common in the early days and pretty much what you get out of Udacity. It's true that they train to the platform but there really isn't another way to get e.g. Sebastian Thrun out there anymore. Another view may take that as a broken window, however.
