No, but they are replacing bad ISPs.
I have a relative in Brussels, while there is 10gig fiber on a nearby street, he's stuck on 100/10 coax, and to add insult to injury, Starlink is cheaper.
What I'm saying, is as soon as there is a real competitor pressure, ISPs can upgrade their deployments in under a year or two, even without touching buried copper. Of course they can also choose not to do that too :) .
On the other hand : "Starlink users typically experience download speeds between 45 and 280 Mbps, with a majority of users experiencing speeds over 100 Mbps. Upload speeds are typically between 10 and 30 Mbps."
That doesn't sound meaningfully different. What is the price difference ?
And come on 100/10 is not bad despite the other 10gig fiber
