It's as old as any "service" has existed, nevermind internet.
If you go into a store or cafe and start shouting at the top of your lungs, the owner is free to refuse service, kick you out and/or even ban you from ever entering their store again.
What's the difference between that store owner and an ISP?
You're free to go to any other store that will have you, and is ok with your shouting. If it turns out there are no stores ok with it, whose problem is that? Should store owners be prohibited from refusing service to anyone, no matter what their behaviour?
You can start your own store, so long as you can pay rent, have suppliers that will sell you goods, etc - but again, no one is obligated to do any of that.
(I get there's protected classes that prevent discrimination based on things like age, gender, ethnicity, etc, but that's a separate issue, and tangential to their behaviour which is what we're discussing here.)
