It's my understanding that 1000/30 isn't an artificial limitation. The coax lines have limited bandwidth such that 1000/1000 per customer just isn't possible. They could split it different ways, of course, but since historically most customers download far more than they upload the 1000/30 became standard among consumer ISPs.

Not that ISPs aren't evil. They were paid to run fiber everywhere, such that everyone would have 1000/1000 fiber links by now. But such as it is.

DOCSIS is asymmetrical, but my understanding is that 3.1 could theoretically handle 10000/1000 with all channels. I’m sure the infrastructure in many places wouldn’t be able to do that, but I have a feeling they could do better than 30.
