Unless it's a deep pocketed behemoth coming and stomping out local competition because they can afford to lose money on price dumping.
Though I agree with the general idea of the competition.

I really wish microeconomics was a required course in high school or primary. I find it to be one of the least understood of the well-established fields, and one that matters when we get older and vote or debate on these topics.
Given how common it is for politicians to pass bills directly written by corporate lobbies, yes. I think exactly that.
Usually when there is a deep-pocketed entity stomping out local competition they are using regulatory capture as their main tool (this is what Comcast seems to do) and the problem is competition has been made illegal.
In situations like this, my default assumption is that it is illegal to lay competing cables until proven otherwise. We had a similar situation of massive monopoly provider in Australia back in the early 2000s, the economics didn't stop new companies laying new cable to compete with the incumbents. That all died when the government launched a new national network though.
My current connection in Brisbane is 1GbE download (incredibly fast for Australia), but only 50mbps upload. That 50mbps upload is the fastest commonly available speed in the whole country. Most ISP's don't offer anything faster than 20mbps. :(
Reliability isn't great either. Had an 8 hour (!) outage overnight about a month ago, then a ~2 hour outage last week. Both caused by NBN Co, rather than my ISP.
The concept of hosting anything actually useful or important from home infrastructure is just laughable when there are commonly multi-hour outages. It's just fucking stupid. :(
I somewhat remember them from years ago, before I moved overseas for a while.
