I think the real cause is they don't want to promote a different platform (i m thinkin g+) as the mainstream source of content stream, and supporting RSS as a protocol is only going to dilute that goal. Even if they were making a profit on reader, they would still kill it (unless it's fuck-you profit, which it certainly isn't).
I don't agree with their goal, but since i m not a google customer, and i don't pay them money, i don't get to decide their goal.
