Why is Comcast blocking things? That seems like it’s out of scope for an ISP.

For Internet access, sure. But ISPs also have value added protection services and this part of an optional content 
filtering service that is integrated into the leased Comcast gateways. Users can turn on things like parental 
controls, including time limit and time-of-day boundaries for certain devices (e.g. cut off kid's game console 
Internet access at midnight on school nights). See

Yes, but it’s tragically opt-out instead of opt-in as it should be. That means that anyone whose site happens to get 
miscategorized by them gets the added costs of dealing with the user complaints instead of Comcast having to bear the 
costs of their error.

It’s a classic example of the toxic polluter business model. Do something stupid while making sure that the costs of 
your errors fall on someone else.
