I agree, but I prefer it when they're at least upfront about it. It's much better than just silently collecting your data and then using it against it you in ways you'll never know or be able to trace back even if it's suspected. If my health insurance premiums rise suddenly, it'd take a whistleblower for me to discover that it was because my face was flagged more often at fast-food counters or bars.
