I have an email from Anna with Easy Languages saying that we have permission to use their videos on the website. "You’re welcome to embed our YouTube videos on your website or include a link to one of our channels in your course or curriculum free of charge
However, if you’d like to download and re-upload one of our videos to another platform, you’ll need to purchase a license from us. Our prices for 5-year commercial licenses start at 600€."
