A major difference between the utilities you've described and YouTube / Facebook / Reddit / Twitter is inescapable monopoly. Barring special cases like well-water or local power generation that most people don't have access to, if the utilities cut you off, there is no alternative source. If YouTube cuts you off, you can go to another video host (including but not limited to paying for your own computer to host your data). If Facebook kicks you off, you can use email. Hell, if Facebook or Twitter kick you off, you can go use Twitter or Facebook.
