Why?

No need JAVA --- No lags.
Easy to change btw games.
Speed connection.
Sub players need something more then unsub players.

Switching between games is still possible for subbed players. Moreover: you now have much more games to choose from.

Subbed players still have the benefits they used to have (in fact more than that)

The Java problem always gets ignored. :)

I gets ignored 'cause it was still java.  Only then it was bundled up together, "compiled" into a single binary.
