FCC Votes to Kill Net Neutrality

https://techcrunch.com/2017/12/14/the-fcc-officially-votes-to-kill-net-neutrality/#

Could someone please explain "net neutrality" to me?  I find it all very confusing.

Before, ISPs had to treat all websites and services equally. You couldn't throttle (or heavily slow down) websites that didn't pay more to the service providers. Now, they could. So Netflix could be faster in an ISP, but the same provider could slow down a competitor because they didn't pay the ISPs enough money. 
Nothing has actually happened yet, but when it does, you'll notice - most of the country is served by maybe two ISPs at once. Usually just one.

From what i've read, this vote to end govt involvement in the internet is good.  I know, I know - the media tells everyone to be fearful and this will be awful.  But when has the govt run ANYTHING well, fair and cheap?  Never.  So to get them out of it is good.

The free market will eventually fix any "throttling" or "price fixing".  In fact, in the few years that net neutrality was in effect, there was plenty of evidence of these 2 practices anyway.  As one govt official put it (I'm paraphrasing): "Net neutrality was only in existence for a few years.  Before that, the internet ran fine.  We don't need the govt get in the way."
