Googles behaviour is indefensible
This passage is an example:
Market dominance is, as such, not illegal under EU antitrust rules. However,
dominant companies have a special responsibility not to abuse their powerful
market position by restricting competition, either in the market where they
are dominant or in separate markets.
Google has engaged in three separate types of practices, which all had the aim
of cementing Google's dominant position in general internet search.
1. Illegal tying of Google's search and browser apps.
2. Illegal payments conditional on exclusive pre-installation of Google Search.
3. Illegal obstruction of distribution of competing Android OS forks.
