For a few months now, users from Finland have been complaining that Google Maps Finland is in Swedish and not in their native language, Finnish. A Google Maps Help thread has those complaints.
A Googler even responded on May 26th, saying, "This is an issue which I reported to our team for their review and resolution." Another Google replied three days later, adding "we know this is a problem and it's definitely going to get fixed. In fact one of the engineers who works on tile rendering is Finnish, and is as happy about this bug as you are."
A few months later, still no fix and loyal Finland Google users are upset, to say the least. On July 14th, Googler, Adam said that it was fixed, but it was not fixed. I personally don't speak the language, so see the thread for more details.
