Agriculture moves a fair amount of data around. You probably don't need 25 Mbit today, but need more than the ancient infrastructure can supply. The infrastructure being built to be capable of closing the latter gap is able to handle much more both for reasons of accommodating future needs and simply where the technology is now for modern installations.

And for that reason, as a farmer, I can get gigabit service on my farms, but where I live in an urban area where the infrastructure isn't as old and is still moderately capable I am topped out at 50 Mbit service.
