If I believe the media that this leaked memo might bring attention from the DoJ back onto Google over the anti poaching agreements then the leak and it's contents are bad news.

If I'm trusting Google with my data then the termination of the employee for violating their code of conduct could absolutely be viewed as good news.

Any of this being good or bad is completely dependent your view point and how it might affect you. If I'm a shareholder I'm glad the employee is gone and not necessarily happy that the DoJ might take a closer look at the company or estimated billion dollars this will cost each year. If I'm a potential Google employee I'm probably a little bit wary about the termination and glad that they are paying more competitive salaries but potentially disappointed that future bonuses will be reduced.
