Manu Cornet left Google earlier this month, but no one has any problem with snark like this. Not management, not HR and not every day Googlers. Some things can’t be said, mostly personal attacks, but the freedom to say critical things very snarkily is completely there and no one thinks anything about it.

Compared to some things that are said and published internally, Goomics are quite tame.

You should see the internal meme board, some of the criticism there is a lot stronger than these comics. If you fire everyone who's critical of the company, you'll only end up with yes-mans and the company will be ruined. As long as the criticism is constructive and legitimate, it's very welcome from my experience.

He left a few days ago, but as far as I'm aware, nobody is going to get fired for a comic at a well functioning company.

He quit this week, hence them now being public.

The author is very well aware of what can be laughted at and in what way. If anything, the author could be promoted for promoting the key talking points in a somewhat elegant way.
