Is it surprising? They increased the price of their primary product by 30% - so it should follow that their revenue should also increase by some similar factor (modulo whatever percentage of revenue is from CI minutes or the other plans which didn't increase in price, like - notably - the enterprise plan which is still $99).
Based on their last Quarterly Earnings report [0], it looks like subscription revenue is on the order of 10:1 compared to other revenue.
