Tech companies design their websites the same way. For example, when you you want to look up a Facebook event happening tonight (your reason) the Facebook app doesn’t allow you to access it without first landing on the news feed (their reasons), and that’s on purpose. Facebook wants to convert every reason you have for using Facebook, into their reason which is to maximize the time you spend consuming things.
For example, in the physical world of grocery stories, the #1 and #2 most popular reasons to visit are pharmacy refills and buying milk. But grocery stores want to maximize how much people buy, so they put the pharmacy and the milk at the back of the store.
