What they should do is collectively take their content somewhere else.
As an aside, I'm seeing the same pattern at Amazon. People thought they were opening a business on amazon selling retail. Then amazon started selling the profitable products themselves, storing the products themselves, ... basically doing more and more of the work and taking more control and taking money from the people who helped them become powerful. Businesses there are now devolving into repackaging jobs.
Now Youtube is doing the same. They used focus on being a search and distribution mechanism. Now they produce content, allow sponsorships, have more ads per minute of viewing then television, ... jobs there are again, repackaging jobs. Repackage scenes from movies, previews, upload documentaries, sports clips...
They both grew through the expansion of the long tail. The reality is: where are people in the long tail going to go to sell their repackaged stuff?
Nowhere. There's no other amazon. Ebay? The flea market of the internet? That's where people who wanted to sell to wal-mart go.
The only place for them to go would be to create their own online store, or their own website where people can watch their movies. Then you have to be found through...
... that's right, Google. Nope. That won't work either, because only AdWords sponsored content appears in Google searches anymore. Google wants you adding data snippets to google.com so people won't even visit your website.
The internet has turned to garbage. You're better off going to the library like the old days.
The internet has been ruined by the mainstream and the money grubbers.
It's just gross. So sad.
