Why Google/AWS/Azure's bandwidth is 10x more expensive than competition?

Cloud provider bandwidth pricing:

  Google Cloud [1]: $0.105/GB (max) - $0.06/GB (min)
  AWS [2]: $0.09/GB (max) - $0.05/GB (min)
  Azure [3]: $0.087/GB (max) - $0.05/GB (min)

  Linode [4]: $0.02/GB
  DigitalOcean [5]: $0.01/GiB
  Cloudflare [6]: Freemium (but they can suspend you without warning)

In comparison, I pay ~60$/Month for 1Gbit/s up/down internet at home, which means ~$0.0002/GB, which is 300x cheaper than Google Cloud's bandwidth.

How is this possible? Is it purely because of the top trio's market dominance? Or competitors are just taking the loss to get attract customers?
