The internet was the pinnacle of a series of benign regulatory choices, clear and present dangers of older models being avoided, and lack of incumbent awareness, and adaptation.
This era has ended, we are in the end game, and how America fights and sets an example here, <despite> all odds, will influence how this resource gets used for generations.
This is not a fight you can give up.
You may have to build your own last mile internet infrastructure. (See comments below about mesh networking)
I assume T-Mobile will join in on this zero-rating of data, based on their "all you can eat" promotion. You may not be able to use a cell phone in the US.
Boycotts do get the attention of the company, but it's going to take a long time and a lot of hard, hard work.
But it must be fought.
The fact that America fought for it under wheeler and the previous administration was at the very least an example to point out the hypocrisy of Facebook, and an example of the country which created the internet valuing net neutrality.
Maybe/perhaps Coders/computer scientists/computer engineers need a body to govern ethics, and that body needs to make the moral and clear call on net neutrality.
There are countries in Europe, the South Pacific, et. al. where carriers offer "free social" where they don't charge for Facebook and Twitter. Wikiepdia is offered for free by some African carriers; which allows them to also benefit from a lack of real network-neutrality.
When it comes to media and freedom vs industry, I think this video from the mid-2000s explains the situation best (in terms of network neutrality):
This is not something one needs to 'keep in mind' to conclude that commercial entities would end up controlling and administering it.
