Fuck it, let’s just ban any and every app that involves or simulates currency and uses chance as a mechanic that interacts with that currency.
Tokens that can be redeemed for a chance of a cosmetic reward? Gambling.
Credits used to pay for upkeep of an LLM that may or may not generate an expected output? Also gambling.
Subscription for a service that promises XYZ and delivers less than 100% during its service period? Believe it or not, gambling.
The speech recognition software used by digital assistants that come with most modern smartphones would make it trivial to process the audio locally and map the output to your ad profile. Much lighter lift than sending audio recordings.
