There seem to be legal problems with them in Germany or is it some European law and other countries are also blocked? Does anyone know what exactly the problem is? Just potential copyright infringements from audio in the background e.x.?
It is a stupid law in Germany. :(

"Because of the German law (RStV), you must have a broadcast licence from the media authorities when you make a live stream that can reach more than 500 people at the same time. Not getting one would result in a fine of up to 500 000€. However, even if you would have one, Google might need one as well (because they somewhat are the "television channel") and they don't have one (if you do stuff that is against German law in your live stream, Google would lose its licence because of you)."
I seem to recall reading that the German audio royalties law forced streams to pay royalties to the industry association (RIAA equivalent) even for creative commons music. I could be misremembering or misinterpreting, so if someone could provide an up-to-date reference it would be appreciated.
