I've read part of the complaint, and it is fairly persuasive, but I do feel like most of Google's actions that "reinforce" their monopoly are somewhat morally acceptable. Like Google requiring Android manufactures to use Chrome and its search engine as default or Google paying Apple to make its search engine the default in iOs. Google is spending most likely billions on developing and maintaining Android and thus deserve to impose some financially beneficial requirements. However, Google blanket banning manufacturers from forking Android instead of just prohibiting Android-forks from using "Google Play Services" is clearly anti-competitive and shady.
