I feel most peertube users would not care. But is it legal, or a chance that some one might sue?
edit: added claritiy to the question title and post body.
Peertube is an open source platform where I feel most users are posting there just to have fun and as a hobby for no or little profit. While Youtube is ad supported and creators on there now days want to use it to make profit.
On Peertube should it be legally acceptable to download uploaded videos for free for offline use? Is it legally acceptable?
Streaming makes a copy of the video in your browser’s cache, so it’s legal for you to make a local copy to watch unless the server or poster is breaking the law by posting the video. Unless there’s a license accompanying the video that specifically says something about not storing your local copy long-term, it isn’t illegal to do that as well.
