It's not that fewer problems happen, it's that different problems happen. The 'classic' problem of government surveillance is that the governments are able (and too often willing) to resort to force.
A distinct problem of surveillance capitalism is that someone in the business of selling surveillance is incentivized to invent new markets to sell their product to and new reasons for their customers to buy. Furthermore, if they're successful, that gives everyone else an incentive to copy them.
Inside a dystopian totalitarian government, a ministry of surveillance might push to increase its own influence, but it would never tolerate competitors.
