As you stated, I would imagine that the ad networks see people like me as a very small minority. However, there are particularly notable exceptions. There are ~11.5 million Catalan speakers in the world, and most of them in Spain. While the majority of Catalan speakers can also speak Spanish, they are extremely defensive of their language and you will find most road signs, governmental correspondence and general communication in Catalan as well as Spanish. Most Ad networks will shoe-horn these users into Spanish ads. I imagine some Catalonians find that practice offensive. When you compare the number of Norwegian speakers in the world (~5 million), it puts things into perspective. In actual fact these ad networks are missing a pretty big slice of the market when you add everything up. In Europe there are huge migrations of different nationalities. In a very short time the numbers of Greeks who leave Greece for other European countries will start to sky rocket. This open migration throughout Europe means that this problem will only get worse, and the numbers of people being mistargeted will increase. That is what I would call a market niche (or unique selling point) that is potentially up for grabs.
