In the morning, you check email. At noon, you browse social media and message friends. In the evening, you listen to music while shopping online. Around bedtime, you curl up with an e-book.
For all of those activities, you probably used a product made or sold by Google, Amazon, Apple or Facebook. There’s no simple way to avoid those Big Four. Even if you subscribed to Spotify, you would probably still be using a Google Android phone, an Amazon speaker or an Apple iPhone to stream the music. Even if you deleted Facebook, you might.
