Is this question a trap? Isn't it rather obvious that Apple, a company that has never really had a business model built on surveillence, is less offensive than Google in this regard?
Ok, on second thought, that's an infinitesimally small risk.
So you're right - Apple could always go down a bad path. But because of their respective business models, I'm more confident in Apple than Google.
Google doesn't have any products that are similar. Google mostly only answers similarly to shareholders if ad revenue is down. It would potentially take a lot to change in the world for any product to rival Google's ad revenue in prominence on shareholder reports.
