1) Inertia. The Indian market is largely English-speaking, so many products came to market in English first, and now people are used to it.
2) Colonialism. Using English still marks you as "educated" and "more respectable". So, to not look like a yokel, everybody sets their UI to English. Content, which is more ephemeral, still is successful in Hindi/Urdu.
3) Localization is hard, and often the English localization is better - but content isn't localized, its first language is the native language.
IIRC, most browsers do default to the OS language. It's just not the correct choice in all cases :)
Websites doing weird things is websites trying to be smart and failing on top of that.
Same happened in Pakistan, the higher up the social ladder you go, the more likely you stumble on somebody who simply can't do written Urdu, or even speak it.
