I would not hurry up blaming the prices.

We can have a look at USA with probably the most expensive internet / mobile plans and worst internet (excluding undeveloped countries). On the other hand, there are many emerging EU countries like Lithuania, where you can get stable 4G across a country for 5 eur/month.

Of course prices are not the only reason. Population density, local monopolies, legacy infrastructures, etc. also play a huge role in quality of access. But I don't think the idea that price wars take a toll on quality of service is particularly controversial.
