Apps that tempt people into placing their mental health issues, and the state of those issues, into networked devices designed to collect and leak their private data like a sieve is just irresponsible. I'm sure advertisers and data brokers would love to have this kind of information, but it's probably better for people who already have struggles with mental health if companies aren't exploiting those struggles for pr…
Maybe touching some grass and freeing yourself from these shackles would actually improve your life? Constantly worrying if some data is gathered you that could be used to gasp better target advertisements for you probably is affecting that mental state a lot more than you can to admit.

You're either confused or grossly misinformed. It's never been just about showing you ads.
The data collected about you can and will will be used against you in countless other ways. Data brokers sell your info to employers, landlords, and insurance companies. Your private data can be used against you in courtrooms, in divorce proceedings, in custody battles. The data apps collect can get you arrested or make you a suspect for crimes you had nothing to do with (or are only crimes in other states).
Companies are increasingly using your private data to determine everything from how much to charge you vs the next person for the same goods/services, to decide what they'll tell you their policies are vs what they'll tell someone else, and even how long to leave you waiting on hold when you call them.
The data being collected and sold about you never goes away. It will follow you for the rest of your life. You aren't allowed to know who has it, or what they are doing with it, or how accurate it is. You can never know what will prejudice someone against you and what is acceptable today may not be tomorrow.
If you think the data being collected about you is all about what ads you see, then you clearly haven't been paying attention. There is a multi-billion dollar a year industry around the buying and selling the most mundane details of your personal life because not only is your data "interesting", it's making people money hand over fist at your expense.
