LinkedIn is a "professional" social media website best known for its dark pattern in misleading users hand over their email login credentials to LinkedIn, allowing them to scrape their contacts list and uploading that to LinkedIn. This "feature" was around since 2010 to 20??.
LinkedIn also makes it difficult to cancel their free trial membership, preying upon users forgetting or not being able to locate the cancel page.
LinkedIn's membership price has also quintupled from $10 per month in 2018 to $50 in 2024.
