It makes perfect sense that govs control names within their jurisdiction - I am eyerolling at both the name change and the reaction.

I am curious though - is it convention to leave the data as is, or is it illegal to modify it?

Regardless, itll just be changed back in 2 years; as long as I can type "lake ontario" and get directed to Lake Ontario, I do not care at all what the gov database calls it currently.
