Yes they do, they are bound by a small handful of 'companies' or services that provide streaming media. These companies have been and continue to draw in substantial benefits from these services. Something I don't see just going away soon , simply because developers are much more interested in revenue themselves, utilizing what is already available to stand upon when building their idea.
This is a level of development that is on another playing field than streaming media. Which is far less formidable when deciding to delve into one of the largest markets in social media revenue. Why be concerned about these little details, when all that needs done is to find an opinionated / knowledgable demographic, in any given niche to draw in viewers slash clickers, then utilize one of the several already widely used plugins for video. Just add a small script and you have instant website.
This to me is a major failure of ingenuity let alone individually prospecting ones own creativity. I mean look around , you can go from one site to the next, which is more or less the same thing , different layout different coloring and a few features that vary slightly. Not much new. We are bound and stuck in the mud by our own complacency.
