Never mind ez. gg as a thing needs to die a death.
It's the lamest possible way to express good sportsmanship and civility.
I've had online games of netrunner where I won or lost incredibly quickly and with no chance it ever could have gone any other way (due to bad luck or just generally being terrible at the game/having a crappy deck) and it always gets with a gg (if I was the one who steamrolled them then they also immediately disconnect before I even have a chance to commiserate for their bad luck)
Clearly it was not a good game for anyone involved, don't pretend it is, assbrains.
