You are lumping all big companies under the same umbrella, which is incorrect.
The internet service providers like ATT, Verizon, Sprint etc, they hate Net Neutrality. Under NN they can not charge you extra for watching Netflix, they are forced to allow all data to flow freely and equally over their networks.
Netflix, Amazon, Google and others want NN because it ensures their content does not get charged extra by the cable providers.

This is an example of the power of misinformation.
Verizon and Ajit Pai made up all this nonsense that deregulation will allow the little guy to compete and that is healthy for capitalism. That was a lie.
A few years back all of us here in Raleigh got mail from Google fiber that they were coming to our neighbor hoods, I even got the t-shirt!
Where is Google fiber now?
They were blocked at every step of the way by AT&T and the incumbent cable providers.

It got to the point where it was simply too expensive for Google to fight with AT&T and the other existing ISP's, so they simply stopped.
There is no competition in my neighborhood, its a duopoly between AT&T and Spectrum. Neither bothers to give special deals or undercut the other, they are perfectly happy providing the same service for the same price.
Regulations did not create the monopoly, the big guys were already entrenched and rigged the system so they could not be challenged. All regulations did was prevent them from making even more profits by charging Netflix extra for using their pipes.
As for your comment about the govt having a bad track record, that makes no sense. We had NN and it was fine, the regulations making internet a common carrier like water and electricity work, and they work great! No consumer was crying about the fact that they could watch Netflix and Youtube and not get throttled by their ISP. We all loved the fact that all data was treated equally over our internet connection, that is a great track record!
Im not sure why you see that as a bad track record.
Here is a bad track record, Time Warner Cable being sued because they throttle League of Legends, as they now can because there is no net neutrality:

In summary:
Net Neutrality FORCES ISP's to treat all data equally! It is a great thing for consumers, but a terrible thing for the ISP's.
