Once upon a time, you could have yourself a nice little Saturday of stocking up at Costco (using your sister's membership card, naturally), before hitting up a museum (free admission with your 15-year-old expired student ID) or settling into a reality TV binge sesh (streaming on your college roommate's ex-boyfriend's Netflix login). Thanks to the fine-tuning of the tech that Corporate America uses to police subscriptions, those freeloading days are over. Costco and Disney this month took a page from the Netflix playbook and announced they are cracking down on account sharers. Want to put on "Frozen" for the kids so you can have two hours to do literally anything else? You're going to need a Disney+ login associated with your household. The tech that tracks your IP address and can read your face has gotten more sophisticated. Retailers and streaming services are increasingly turning to status-verification tech that make it harder for folks to claim student discounts on services like Amazon Prime or Spotify beyond graduation. Cracking down on sharing was hugely successful for Netflix. For years, the streaming giant turned a blind eye to password sharing because doing so allowed more people to experience the product and, crucially, come to rely on it. Netflix kept growing and growing until 2022, when [it] cashed in on its brand loyalty, betting that it had made itself indispensable to enough viewers that they'd be willing to cough up $7-$15 a month to keep their access.
