The official PDN website has multiple giant fake “download” ads. Then if you manage to click the real download link it opens up a full screen interstitial ad that is also a fake download link. Close that out and you drop onto the “download” page, also full of fake download ads. Click through to “download from dotpdn” and enjoy yet another full page of fake download ads. If you make it through all this and then manage to click the real download link it’s just a link to the installer hosted on GitHub, which should have been linked from the main page.
This is all intentional and very scummy. I understand ads, but this is excessive and all the ads are at best some sort of bloatware garbage if not actively malware.
