It takes a lot of energy to move a happy customer from one network to another. Starlink's service will have to either be really really cheap, or super fast... and quite possibly a combination of the two... to get people to jump ship. On top of that, the installation is going to be more like a WISP install then a satelite installation. I think that there's a chance that the WISP industry could make money if Starlink allows us to resell or at least perform the physical installation of the service to clients. I'd rather sell Starlink service to someone I can't cover and make a little bit of $$ then sully my reputation by selling a traditional satellite internet service like Hughs/Viasat/Wildblue/etc. That's another thing... satellite internet has a bad repuation and it's going to take a lot of PR and marketing $$ to get the ball rolling on this.
I think we could potentially make lemonade from this lemon of a situation.
