Ramachandra Guha spares neither left nor right and gives some insights about promotions in government service in this Telegraph article(via Guru):
"I come, finally, to the rank careerism displayed in connection with this most contentious deal. On August 12, a Delhi newspaper published a leading article with the title “Trust the Treaty”. The caption gave away the line of argument. But what was significant was not what was being said but who was saying it. The article was written by S.K. Singh, at the time the governor of the Indian state of Arunachal Pradesh. Seeing his byline, I rang a friend in Delhi. “Surely it is unconstitutional for a serving governor to go out and bat for the government like this?” I asked. “Treat the article not as a violation of constitutional propriety but as a job application,” answered my friend. “He wants a bigger state.”
He was right. It was not just that his transgression was not noticed; it was actually rewarded. In the reshuffle of governors announced last week, S.K. Singh was shifted from Arunachal Pradesh to Rajasthan — a more populous state, a much more important one, and closer (in all respects) to Delhi."
This may not be very new. I remember a prominent mathematician who refused to sign a petition for mathematician activist Banwari Lal Sharma's release during the Emergency.
