Congratulations, you just said in 3 sentences what previously it took you 9 paragraphs and a misleading title to do.
You answered your own question, and pointed to several companies doing it in ways that are very public and which are well understood by the /. audience.
You didn't bring any new understanding, and you didn't prompt a meaningful discussion with an open-ended question. You simply ranted for 9 paragraphs about how Streaming and DRM collectively suck because you personally can't pre-download specific content from certain specific services.
Tips:
Tailor your questions to your audience. If you know the answer already, the /. users probably already do as well. When that happens, rewrite your question to be open-ended!
If your goal is to encourage discussion, ask the question, and then step back to let your audience answer it.
Use the right terms, don't redefine them to mean something else just so it supports your argument.
Overall, you would have gotten a lot less flack if your post was:
What's the future of digital media delivery?
With recent focus on streaming media services, customers are caught in the battle between content producers and network provider data/bandwidth caps. Will more streaming services build in local caching like Spotify or Google Play? Will we see the end of DRM-protected content like iTunes? Will DRM become enshrined in cross-service standards like HTML proposals? Does anyone manage this problem well and make money at? Is the idea of personal content libraries dead? Is streaming a sustainable business model?
Everything you said in your original post would have been brought up and compared in the discussion threads and /.ers would be appreciative of the discussion instead of badmouthing your writing abilities and your non-argument.
