Regulators raid Intel, DSG in Europe – managers are helpless against antitrust lawsuits?

EU regulators raid Intel offices on Tuesday. They also raided some of the big electronics retailers, DSG and Media market, in EU. This has become a regular practice of the regulators in the EU to raid offices of some of the big retailers or OEMs. EU is becoming difficult market for the big companies to operate in. Microsoft got so much tired of the lawsuits in EU that it conceded defeat after fighting for many years and paying millions of dollars in penalty. On one side companies need to fight with the regulators on the other hand market is not growing anyway. Manager doesn’t seem to have any option to fight with this. Shareholders of the companies demand for the more profit and bigger operations and growth in every sense. When the managers try to do this, they are accused of the monopoly and all. It is very difficult for a company to avoid become monopoly when the customers like the product/service of the company and how can managers say no, we don’t want to grow anymore. One of the solutions to this problem is to keep diversifying the business of the company. But even this is not a viable solution because once the regulators start investigations; they keep broadening their scope of the investigations. For example, in case of Intel, they started with investigations for the possible contract with the OEMs of the computers but now they are also investigating relationships of the Intel with retailers.
I just wonder if managers can have any solution to avoid with these antitrust lawsuits.
