Why do you say that? It’s perfectly possible to download a file sequentially while uploading parts of it. Although I guess the ending would be harder to find than the beginning... but if all they do is make the first half part more widely available, I don’t see the issue.

I think the issue is that it stops uploading when you're done watching the movie and close the tab. It would be less of an issue if it somehow continued seeding for a while afterward.
