Unless of course you've promised the content owner that you would be
encrypting each delivery with a different key (because they'd been
burned before by things like DVDs, which do not). Then not "problem
solved" at all.
You're also assuming that every customer is viewing the same
bitrate/resolution/aspect ratio. With multi-bitrate streaming, there's
often low overlap between the segments adjacent customers wish to
load... even if the content is not encrypted, or is encrypted with the
same DRM key for everyone.
Of course, the facts of the situation don't appear to matter really...
