I lived in the Philippines for 7 months. The Philippines does not have Net Neutrality.
Most people don't know this, but in the 3rd world Facebook is massive. Few people have PCs or Laptops, everyone has cellphones, and Facebook is the king of mobile. Every store, every service, every person has a Facebook page.
Facebook's largest competitor is Google, and the Filipino government is easily bribed. There is one ISP/Mobile Carrier in Manila, and that ISP has contracts with Facebook. For a mere 5 pesos a month (1 cent), you can get an online data plan with 100% free access to Facebook and only Facebook. Getting a full data plan costs a first-world amount of money few people can afford. Because of this, no one in the Philippines has any incentive to build their own website. No one can access it. No one would know how. They just use Facebook.
It goes beyond that. I paid $70 USD (3500PHP) for 50Mbps Internet (6MBps). If I accessed Gmail, Google, YouTube, Google Docs, etc, my Internet would slow to a crawl. It would take 45 seconds to open Google. Videos would stutter. Facebook? Instantly. Switch to my VPN and hide my connections's source/destination, Google loads instantly again. Faster to connect to Sweden and then to Swedish Google than it is to connect to Filipino Google from the Philippines.
This is specifically what Net Neutrality is designed to protect against. It is not fiction. It is not slippery slope. It already exists.
