>How do they do it?
Because there's no events or content that openly spites its male players. Even White Day both is what it is, and usually has a few token girls participating.

>They did it from the start, so people never expected every character to be for (you)? Incel riots are a result of broken expectations more than anything else.
Nah 99% of the FGO characters are very For (You), even if they have available and present spouses. And even some of those (Irisviel + Kiritsugu) aren't characters who would "offend" the players by being for each other, since that was already the context for those characters in their original story.
