Literally everyone can complain about problems. You can see in the post she has different ideas of how things should be done, how she should be working on different things, how she should be allowed to go to Japan, how they shouldn't use air purifiers, how people should act when a layoff is about to happen, how temp workers should be treated and on and on. I'm not even saying all of these ideas she had are all wrong or bad. But she clearly has solutions and a vision of how Google should operate.
