It doesn't help that dark patterns used by well known websites normalizing the problems. That other day I got a credit card charge notification of $154 from my bank about a charge from Amazon. I didn't buy anything from Amazon recently. I also didn't get any email from Amazon about a bill or a purchase. Logged on to Amazon, looked through the order history, looked through AWS billing, and didn't see any recent charges. I thought my card was stolen and got a fraudulent charge.

By chance I looked into the Prime membership page. An obscure page listed the recent Prime charges. Yep, it's the Prime membership charge. The amount looked odd because tax was added to it, where the old charges were like $119 or $139. Amazon employs a dark pattern of not sending to the users any notification on the Prime renewal, no billing statement, no invoice, no email, just a silent charge on the credit card.

I promptly canceled my Prime membership, not for the money but for not rewarding dark pattern behaviors.
