Negative option marketing
Negative option marketing or NOM for short is a practice in where businesses proactively make changes that restricts users freedom that they may have once originally taking the users silence or inaction to be acceptance.
How it works
A company like a gym may make it super easy to sign up online. But when it comes time to cancel your membership to change to a new gym the consumer later finds out that they have to certify mail the gym to cancel the same membership they signed up for online. While a company could implement a easy cancel option they proactively choose not to keep those who would just accept the cost outweighing the time spent to cancel.
Why it is a problem
Consumer Entrapment
By making the process as easy as possible weather it be creating an account or subscribing to a service users should have a say on if there account should be deleted or a subscription canceled by not providing these options to consumers they are effectively trapped for what they signed up for
Privacy
With relating to accounts since you are not able to remove or delete them those companies may be actively selling that information that you have provided to them to other companies or brokers without your knowledge even if you decided you no longer wish to use the product the info will persist without your consent
