Suppose you are an European citizen and you live in Egypt.
I don't think that is correct. The investigation began in 2015 by Margrethe Vestager. The focus is within the EU. Valve cannot prevent geo-blocking between EU countries. They're free to use IP geo-blocking, but users within the EU must be given the ability to switch to different EU stores. I.e. a Dane must be allowed to log into the Hungary store and purchase games at the local price. This has implications for keys as well, as a Dane must not be prevented from redeeming a Hungarian key, for example.
