So despite how useful this post is, would this even affect me here in the UK?
Almost definitely not. The only place ISP’s have a monopoly on internet traffic is in the “last mile” of connection to the user. There are several routes from US website servers to the UK, so no single connecting service has the ability to impose any significant anticompetitive practices.
Only if you follow any American content creators, or any creators who's fan bases are largely in the US. You can expect to see a decrease in content made, possibly complete destruction of the smaller content creators. A lot of the YouTubers who have high American fan bases will lose a significant chunk of revenue, thus limiting or outright destroying their source of income. Bloggers, Vloggers, fanfiction writers, fan art, there are so many things that it can and will affect. Take a long hard look at the people you interact with on a daily basis on the internet, how many are from the US? How many content creators do you follow or support who have a large US fanbase? If the answer is none to both of those then don't worry about our stupid asses, but if the answer is even one, you should at least share the sites on social media, or bring attention to it in any way you see fit.
