You must have a browser setting that blocks Referer headers or disables JavaScript by default.

Here is the snippet of code that does the redirect:

    <script>
    try {
        if (document.referrer) {
            const ref = new URL(document.referrer);
            if (ref.host === 'news.ycombinator.com') {
                window.location.href = 'https://google.com/';
            }
        }
    } catch (e) {}
    </script>
