The Network Effect described the the GNU Project is when individuals will submit themselves to nonfree and DRM’d software simply in order to socially connect with others. Messaging apps are the textbook example, but video games are as well.
Of course the defense is always a form of apathy or some call to apathy like stating that more people indulge in the activity than those who actively abstain. Of course there is an implicit shaming tactic of those who preserve their freedom, calling them the “frigid minority” or the “isolated zealots”
Shame on you for being so closed minded. The spread of DRM is never okay under any scenario, just because you have some perceived FOMO. There are thousands of multiplayer games out there that don’t have DRM rootkits, why not try to play those with your friends instead?
