You know whats retarded about this, he is talking about doing this on PPC for physical products and the penalty is a google slap. its one thing if google wants to drop your organic rankings because your site is focused on selling stuff, but to hurt you on PPC where you are paying for sponsored ads AND you are providing a likely much superior user experience (by including original content, etc) than the typically found average adwords page (including 'direct linked' advertiser / manufactuer pages), is just terrible.
Google only likes big middlemen, like itself and Amazon, not little middlemen like you.
What's also retarded is there are a heap of videos of google employees out there preaching that site load speed is very important to the user experience.
But even those my eBay aff pages load a crap load faster than eBay's own pages because they're not chock full of shitty javascript (= good user experience), that's not GOOD ENOUGH so NO SOUP FOR YOU!
Original content! You must have original content! Scream the bastards from Google.com, a site that you've gotta search pretty hard through to find some ORIGINAL CONTENT on it!
Don't get me started.
