This is worrying but its not only the laws but enforcement by the companies that's important. There are loads of copyrighted material on streams and youtube but only some companies enforce their rights. If Capcom decided that only one person/company could stream their games then it would be detrimental to their brand. I am sure they know that (Capcom's Solicitors and Accountants excluded

).
Taking Call of Duty as an example. It is all over the web and far more popular then fighting games on youtube. They are incorporating instant recording and uploading into their games to encourage this practice. If somebody in the future was to make big money from streams they might want a share. Modern media companies would much rather partner themselves with companies then restrict them from streaming. For the games companies the price of the ticket is the game. Did any of you see the attempt from Activision to make their own show on COD elite. It ended up so far as no more then celebrity COD with players throwing grenades at choppers. They must have got a TV company to make it. Shiny but sh1te.
Its all about intellectual property and brand protection. If one game makes it mainstream (TV or huge ratings for streams, millions of viewers) as it where then the company that makes the game will want their share and control of how their brand is portrayed.
What can you do? It might mean in the long run, real sponsorship and big prizes and investment. They will always want local tournaments and streams. I still think that the UFC model is the model for fighting games in the future. We are a generation away from the visuals and production of fighting games getting to a level that they will go mainstream but I do think it will happen.
Some of the lads are looking for pay per view on streams at the mo and it is just not worth it for the production and professionalism of the streams.
