Before the concept of "Jagex accounts", you lost nothing if you were a Linux user. This is because you didn't get any benefit from using the "Jagex launcher", for which there are no native versions in Linux. Instead you could, and still can, use the Java-based clients directly without a launcher, and Java is cross-platform so is natively supported by Linux.
But then Jagex decided to reward players for using the Jagex launcher (not sure exactly when they started to do this - I am just starting up again after a year's break). You now get 20 extra bank slots for having a "Jagex account", and hence by using the window-based Jagex launcher.
To be honest, I'm not bothered about the extra 20 slots. The thing that worries me is that this is the first true move against Linux players. I feel that this is the start to abandoning the cross-platform compatibility of the game; e.g., perhaps one day you won't be able to user the Java clients directly?
