Thogapotomus Hosting multiple download files plus all the original ones has to add up.
Thogapotomus I know I'd prefer them to spend resources on new features than hosting petabytes of data that most users will never even realize is there. Or care, for that matter.
The download files are the same files that are used for streaming and the high bitrate files are the master files that SLR will keep hosting anyway. None of those files are going anywhere.
If hosting costs were actually a problem SLR would be deleting the mountain of unwatchable, barely viewed videos they host that were produced by clueless creators. They also would not be adding a bunch of 2D videos that no one is going to watch.
