I've had an idea for a browser extension that can actively warn you when you're dealing with a company that uses dark patterns. For example, say you go to the NYTimes' subscription checkout. It lets you know "Hey, just so you know, they make it very hard to cancel. Here's more info etc." Sort of like an ad blocker. If enough people install it, whoever is managing its database of dark patterns/warnings has the power to really punish companies for this kind of thing. Of course that also means they have great responsibility.
