Last time I checked OpenJDK had no Windows distribution. Given that Oracle bundles adware with their JDK, Zulu means that people like me may no longer have to look at Java as a massive joke.
<gasp> I might even have a JDK on my machine by the end of today.
The adware-bundled installer is provided by Oracle. Whether or not I know better to install adware is irrelevant (because I do, and that's why I don't currently have a JRE installed). Nowhere does Oracle indicate where you can get the JRE without the adware bundle. Your comment is the first time I have read that such an installer exists.
What is relevant is Aunt Tilly's experience - as any HN user should know. She is told by something that she needs Java, goes here[1], clicks on the first link and gets adware. That is victimizing the ignorant and is why I do not take Oracle, and by association Java, seriously. That is why Zulu is exciting - because maybe now I can correct that perception and start doing some Java.

This is great news for Windows users.
