What's the reasoning? That people won't switch away from the more expensive, slower, less reliable service if you get there a bit later?
Starlink isn't wildly expensive, nor is it unreliable or slow, but it loses the comparisons.
See the reason Google Fiber existed [1]. It wasn't for a product, it was to kick the pants of all the monopolistic broadband providers. Now, you have similar motivation on a global scale.
When a telco provides poor quality service somewhere, people have no choice but to pay them as price takers. When there are options, telcos have to provide better service to win your business. Telcos with monopolies have always been rent-seekers. It happens time and time again that some newcomer comes up, and just the hint of competition gets Verizon/Spectrum/etc to suddenly build new tech and dig some trenches.
