The WWW works best when used as intended: decentralized communities that encourage people to be creators rather than consumers.
Instead of Facebook, participate in independent online communities around your interests (for example, forums).
Instead of chat apps that attempt to envelop everyone you've ever met into monolithic walled gardens, use SMS and email.
Instead of Medium, learn how to create your own independent blog with something like Metalsmith, Hugo, or Hexo.
Etc.
