Honestly, in contrast with a lot of people here I'm less certain this was against OpenAI specifically, but that's partially because OpenAI promptly went and said they were going to do the same thing. If anything, I'm more unnerved that it's a general movement away from sharing research - and we've seen the damage this song and dance does before. Frankly I'm disgusted with both OpenAI and DeepMind at this point.
