An awful lot of the content on this website shows naivety/lack of understanding of the website, and in a few cases, displays information which is simply untrue.
http://darkpatterns.org/british-airways-distract-from-cheape... - I'm pretty skeptical that this had any malicious intent. It is showing the cheapest option in the column. Often the customer will already know which class they want to fly in, so it helps them to be able to skim down a column looking for the cheapest option.
http://darkpatterns.org/directline-com-july-2010/ - Hilarious. If this website had any idea how much negative impact price comparison sites have had on car insurance in the UK, they'd be praising Direct Line for not lowering themselves to the tactics of all the other insurers (offering an incredibly unprofitable first year rate, then massively increasing pricing when you renew)
I'm sure there are more - these are the most clear ones after skimming through about half of the categories.
The one exception is the British Airways site. That page is very confusing. At best is awful UI. At worst it was created to trick the user into purchasing a more expensive ticket.
I totally agree that the UI is absolute dogshit, but I don't think I'm willing to definitively call this out as a dark pattern when it definitely could be shitty design.
That's my problem with this website - it would have more impact if it was more honest/genuine and only called out websites which are definitely 100% dark patterns. Or perhaps they could show questionable websites further down under a slightly different heading - to show that they do recognize it's not black and white.
