Amazon’s now-legendary “Prime Day” is July 8-11. Much like Black Friday or Cyber Monday, this means sales on lots of items on Amazon’s vast marketplace, and as such many people flock to the giant’s website to get sweet deals on everything from computers to small kitchen appliances and more. While many of us are feeling the financial crunch more than ever, I urge you, dear reader, to resist the allure. I don’t typically have strong opinions about where people chose to shop or how they decide to spend their heard-earned money, but in this post I hope to lay out a convincing case for why Amazon is full-stop evil, no caveats, and is undeserving of your money on a moral and ethical level no matter what your values are. Amazon needs to be stopped, and legislation will not do so. Only its loyal consumers – who keep the beast alive – can do that by taking their money elsewhere. No matter your political or personal beliefs, I'm certain Amazon violates them in one way or another, and you should vote with your dollar by buying from other places whenever possible. Here’s why.

The car came to rest more than 70 metres away, on the opposite side of the road, leaving a trail of wreckage. According to witnesses, the Model S burst into flames while still airborne. Several passersby tried to open the doors and rescue the driver, but they couldn’t unlock the car. When they heard explosions and saw flames through the windows, they retreated. Even the firefighters, who arrived 20 minutes later, could do nothing but watch the Tesla burn.

At that moment, Rita Meier was unaware of the crash. She tried calling her husband, but he didn’t pick up. When he still hadn’t returned her call hours later – highly unusual for this devoted father – she attempted to track his car using Tesla’s app. It no longer worked. By the time police officers rang her doorbell late that night, Meier was already bracing for the worst.
