While there are definitely some terrible ISPs out there, not every instance of someone not being able to use as much bandwidth as they want is a great injustice.
Sometimes it’s just sane network management. LTE networks in particular are limited in capacity. There are a bunch of different ways to limit use with different tradeoffs, and bandwidth caps actually strike a good balance between effectiveness and predictability. I have a lot of experience thinking about and implementing bandwidth pricing models, and I don’t have time to list all the options and their tradeoffs here, but you can suggest one you think is better if you want. Bandwidth caps cause users to limit their use, while still allowing a user to use the network heavily without penalty when they need to.
The real problem here is that OP doesn’t have an intuitive UX for limiting upload bandwidth to something he is comfortable with. Webtorrent then breaks his assumption that web browsing will not incur upload bandwidth.
It is in general dishonest to diminish someone else's resources without their consent or prior knowledge. I can see how this is different from using someone else's computer as part of your botnet (because the act itself is illegal), but how is this different from, say, mining a bitcoin on someone else's computer because they visited your website?
By "this" I mean the case in which a visitor's bandwidth is used to redistribute a file without their permission.
The solution to this is the same as it is for the crypto miners. Disable javascript and WebRTC by default and you no longer have to worry about every website you visit using your computer for whatever they want.
New tech is really nice and all, but I've never been a big fan of letting everyone and anyone run whatever code they want on my systems. If I actually need a website to do something like this I'll whitelist it or even set up a browser dedicated to that task, but at this point letting every website do whatever it wants is just dangerous.
Terrible internet providers are absolutely the norm across all of America. Except for a handful of small regional ISPs and municipal ISPs, where they haven't been outlawed.
