You are right that they took time to tour Europe by bus (which would have cost a lot of money) to enhance their courses, but thinking about it, they have happily given you (and others) permission to use the outgoing structure, phrases and the audio of their courses.
These video clips - as far as I can tell - are no longer used in their new format.
Would you like me to contact MemRise, pointing out that our considered opinion is - out of respect - not to use the "Learn with Locals" video clips, but would they mind if did we included them?
Thanks for the link @[deleted], which confirms what I thought - it was sponsored.
