I'm claiming it functions more like a doi or other identifier than a sales pitch. I don't think there's a ton of deep thinking involved: there will always be someone who's willing to run a web browser as root on their main system; you can't stop people who are set on something foolish from doing it, but if you can make it more convenient for people who have valid reasons, why not?
This all might be a bit too much serious thought for what was intended as a joke initially (the site, not my comments), though.
Then I'm not sure why you disagree with my criticism - I'm claiming that this page appeals to people who have knowledge in this matter but have not done the deep thinking to have wisdom in this matter. There are plenty of smart people who find "Make X Y again" for other values of X and Y appealing.
