I think they're referring to "maintenance-free" joints, which just means the drilled grease passages (and zirk) aren't there.
It's a trade-off, the joint is stronger without the drilled passages however you also may not know when the grease has leached out either.
I've seen my share of the maintenance joints fail as well, when you pull it open (if it isn't already) one of cups is bone dry.
These cars are just hard on parts, the driveline was never designed with 600hp and a manual trans pounding the hell out of it in mind.
