Comcast started attacking it's customers via MITM about ~2013 or so. Initially it was ads, https://www.google.com/search?hl=en&source=hp&biw=&bih=&q=co... . This would break things like, say, the Steam browser and prevent it from working. I literally had this happen to me. Eventually Comcast changed it's terms of service and violated it's contracts with existing customers and started limiting total data transfer to about 1 TB/mo. When it started doing this it also started MITM injecting JS about your usage into HTTP connections: https://rietta.com/blog/comcast-insecure-injection/

Comcast is the only non-56k ISP available in my area still in 2024. So I use them... but I also have to make sure to protect myself from their attacks. If I did what they're doing I'd go to prison. But some types of legal persons have more rights than human persons.
