not as bad as described, but still: https://www.dotpdn.com/downloads/pdn.html, the linked site to download if not using the Windows Store, has small text "To download, please click the Free Download Now link to the right." at the top, immediately followed by a google ad slot - which at least for me loads an ad with a big blue "DOWNLOAD" button (well, when I turn adblocking and Firefox' inbuild anti-tracking thing off obviously).
