I installed the JRE and JDK (on diff machines) from the downloadable installers (not the updater) and neither installed the adware, nor had the option to.
This makes me wonder if they're doing a partial rollout to some small percentage of users to test the waters.
Same here, installed both JDK and JRE today and no crapware screns.
I guess the target group are less tech savvy users that install it because they don't really know what they are doing, like less law savvy people who agree every terms of use. Kind of shady but accepted practice. JDK users are probably less exploitable.
