Globalization, progress and development of technology, leads to economic power. The unification of European countries strengthens the economies of EU member states and contributes to their development, protection and prosperity. Among other things, the EU directives provide information on the protection of individuals on the market and in case of violation of market rules. There are many theses and antitheses as to what is right and necessary to protect technological power in the market. No, one thing is crucial - how to protect yourself from monopolists in the digital market. It is difficult and very important to be a market leader, and even more difficult to be an honest leader. Microsoft has been using its market share tactics for many decades. For years, it has been building its status and position as the only innovator, but the way it positions itself, most complain that it is unfair. Some complain that it is based on the price, while others say that it is a question of network effects, i.e. externalities, but it remains important that the agreement on the functioning of the EU protects the fair competition of companies both on the internal market and in the interest of consumers.
