I believe the data should add the comparison using purchase power parity. The price in USD being higher in the US than in Brazil doesn’t mean that the internet is more expensive in the US
For example, if a GB is $1 in America and 2 euros in Germany, then we would use a 1:2 ratio for converting the price. So Germany's PPP price would now be $1 in dollars as well. As you can see, this isn't very helpful.
PPP's fundamental assumption is the law of one price, so it's no surprise that all the prices would be the same using it.
