Based on incentives, the government is incentivized to put as many people in jail as possible. Apple is incentivized to make people's phone/laptop experience as good as possible.
Based on worst-case actions, Apple can use your data to 1) sell you more devices, 2) generally reduce your consumer purchasing power, or unlikely 3) sell/share your data and seriously compromise your privacy. The government, on the other hand, can throw you in jail, for life.
