We gave Valve feedback about the impact of the coaching rule after New York, and we will do so again after this event.

The coaching rule has been recently implemented by Valve. It is in tune with their vision to keep the FPS game 5v5 without interference from other sources ( during the playtime). Coaches are still allowed to talk to players during tactical timeouts and between halves, however the constant strategising and being able to communicate seamlessly has been throttled.
