Each streaming video uses the same amount of bandwidth as a video download.
If you stream the video, you can watch it once.
If you download the video, you can watch it as many times as you like.
The internet is slowly being shut down by big government and corporations to control what information you can access. These types of videos will not be available to you at some point.
We encourage you to download the videos and make copies to share with others now, while you still have the opportunity to do so.
