This, exactly. I happen to prefer English to my native language, mostly because I prefer to see the original version of content, not some badly translated version which is all it is a lot of the time. It's extremely frustrating to let websites know I would like to get English content, then be delivered a translated, shortened, bad quality version of the that same content because they think that's better for me. Actually, while it's probably also a limitation due to licensing, I've had the extremely frustrating experience of trying out Google Play Books on my phone. No language settings. The phone's language, the settings in your Google settings and account are ignored. I'm in Germany, I get the books in German. I actually would have bought my first book that day if I could have accessed the original version, but I couldn't. Point is, it's not just ad revenue they're losing out on, but also customers.
