On the whole, it felt like it pushed the company in a positive direction --- internal discussions mirroring #metoo led to more visibility of sexual harassment and accountability for leadership. The discourse around the James Damore memo, as divisive as it was, felt like it still led to a broader understanding of the negative perspectives women in tech had to deal with constantly.
Most importantly (IMO), Google's product choices and politics are not inseparable --- Google is far too large and influential to pretend otherwise, and discussing these topics acted as a watchdog of sorts. Internal discussions about a potential censored search engine product in China resulted in pressure on leadership to change course, and pressure on Cloud bidding on the JEDI contract led to Google withdrawing from that bid.
Shutting off that political discourse feels like it'd be a huge blow to "oversight" from concerned Googlers --- particularly the ones who felt it was worth staying and using their influence internally to push Google toward creating a more just world.
