Chegg Study for university students does not link to a cancel subscription on their website, you have to search google "how to remove sub from chegg" and then you can find a "Cancel Sub" help article on the Chegg website. You can not get directly to the cancel article from their base website. They should be fined for the dark pattern.
Many website I have encountered has similar dark patterns. Its not just chegg but other too like facebook. Most people don't know meaning of deactivate vs delete (and delete even takes like 30 days ridiculous). And many website like Adobe will make you follow series of steps like 7-8 pages. And they try to convince you shouldn't cancel via examples like "Your following services are active you no longer can access them". At last page it was like this "Right now we are offering 30% discount you can grab this easily etc.".
Till its coded to law I don't think we can expect anything from corporation.
