I think people have radically different ideas about what "minimal background information" is.

Some people think the Silmarillion is a suitable primer for their setting.

Some people have like one paragraph for the big picture, and one paragraph for each major faction.

There are players that would say both is too much.

I think a couple short paragraphs should be enough for a quick start for a custom setting, but I've had players that just refuse to read anything at all. As someone else said, it's makes it really hard to do some sort of stories if all the players are utter neophytes/amnesiacs/from-another-world/etc

I tried to do a game of Vampire once, but the players refused to read anything about the setting. All the political intrigue fell completely flat because they didn't understand what the different factions were looking for, nor did they understand how vampires worked.

That group might have just been kind of bad players, but I feel like bad players are more common than good. By "bad" I mean "doesn't think about the game very much, doesn't retain anything about the story or rules". They couldn't really do anything more complex than a simple dungeon crawl.
