One day, you won't be able to delete your social network account anymore. There will be a delete button, but the account will stay, and it will keep posting after you're gone, it won't care whether you are doing something else entirely or whether you're dead, the show will go on.

The shareholders will be content, because they see value in that. The users might not, but not many of them are actual humans, nowadays they're mostly AI, who has time to read and/or post on social media? Just ask your favorite AI what's the hottest trends on social networks, it should suffice to scratch the itch.
