I'm skeptical about whether signing a petition would do any good and whether it'd be worth the effort. If Oracle gave a crap, it already wouldn't be an issue. I expect a lot more people care about this issue than signed the petition. I know I'm one.
I agree with it and don't see why your comment has been downvoted. 6000 people signing is pretty small compared to the scale of Java. That negligible number is more a sign for Oracle that they can bundle whatever crapware they want with Java.
6000 people? The more appropriate subject here would be "Most users don't care about Java bloatware".
