You can stream and not receive hints, or vice versa, not stream and receive hints (if the person giving hints is sitting next to you, or even moving the mouse). Thus, there is no direct connection between cheating and streaming.
If you were using streaming to cheat, your opponent would simply not know about such a stream. This might be an argument for them.

I wouldn't consider our CIS (or whatever) view on this problem to be the only correct and appropriate one. Just as we cannot put ourselves in the shoes of a Western European or a Chinese person. Therefore, we should especially listen to the opposing side's point of view. Especially considering that they have a completely different view on copyright. That's one point.
And on the other hand... Vigo was banned for something similar.
And besides... I watched one stream quite thoroughly, where voices from the chat actually gave valuable advice to the player. And after some hesitation, he acted according to the voices. And this did influence the outcome of the game. The result was achieved.
Wait a bit... The problems are only becoming apparent. There will be bans on streaming, or only with the consent of both players, or streaming by third parties, up to and including refusing to play. However, with a significant caveat - in games played for fun, this doesn't matter.
