See if you can figure out the difference between volunteering anonymized data with the exact level of granularity you choose vs. having all of that data and more involuntarily collected and sold in secret as a consequence of merely participating in the system we are all coerced into if we don't want to be homeless

Isn't levels.fyi or similar just the employee side of the coin?
