Here's a situation. Player A is playing against Player B in a tournament, and Player A is against streaming or broadcasting Player B's game. Does Player B have the right to publicly stream or broadcast? What is the current situation on the forum?

And what position could there be here? Streaming can't be prohibited in any way, and the number of broadcasts can be given to several players personally; this cannot be monitored. The other question is how this stream should take place to minimize the possibilities for hints. Something needs to be done in this direction, and over time, some kind of condition will definitely be developed.
Although, as far as I know, in all games, streams are open, and if desired, the opponent can get important information from it for himself (especially regarding strategies).
