This is the proposed SpaceX internet plan. “Full access to the internet.”
Sometime in 2019, SpaceX will be launching the first of its proposed 4000 satellites to provide ultra high speed internet to the entire world. Elon Musk Wants to Begin Launching SpaceX's 4,000 Internet Satellites in 2019.
Eventually, this internet program will run traditional cable companies out of business.
It’s very clear to me that Musk is a huge proponent of net neutrality and believes that the internet should be as accessible as possible to as many people as possible.It also fits in with his philosophies.
Everything Musk does - Tesla, the mars missions, the Hyperloop, Paypal, etc is to give humans a higher quality of life and to advance civilization.
Removing net neutrality is seen by many as a massive step backwards in our quest to improve the world. And I believe Musk feels the same.
