It's not exactly true. I am from the South and I love Hindi as much as I love my mother tongue (Kannada). However, the reason there are revolts to the degree it becomes National news is primarily because of the thrust of Hindi on locals. What do I mean by that? Imagine a villager or someone not versed in English wanting to fill a form in a Governmental organisation or a Bank. For a long time, most forms were available only in English or Hindi and not in the local language. This naturally pissed that section of the populace as they had no grasp of either of the languages. This felt "imposing" on them.

I call it Governmental failure of either educating the masses with regards to learning Hindi or them being unable to cater to the local needs (not printing enough forms in the local language). This was in turn exploited by the regional parties who converted this issue to a language-war of sorts, trying to portray that the Central government is imposing Hindi and diminishing the local language. These "movements" were used mainly for political gain. The reason you don't see this happen in the North is because for most, Hindi is a natural fallback language as the script is similar (Devanagari) to their Mother tongue, unlike in the South.
