The entire thing is explaining how they are upholding privacy to do this training.
- It’s opt-in only (if you don’t choose to share analytics, nothing is collected).
- They use differential privacy (adding noise so they get trends, not individual data).
- They developed a new method to train on text patterns without collecting actual messages or emails from devices. (link to research on arXiv)
Everyone who uses it will contribute to the dilution. It’s not like 1:1000 dilution from a single person’s shower becomes 1:100 if 10 people use it or 1:1 for a thousand. No, they each will use large amounts of water that dilute it down.
People don’t pour their soap down the sink (at least not for any normal uses); they use a small amount which gets washed away with a lot more water.
I’d suggest finding what concentration things are dangerous at and whether they break down organically or not. Then you can aim to keep your product below that concentration if you can so even if someone did pour it down the drain it wouldn’t be harmful. And if you confirm it will break down, you know you aren’t contributing to long-term build up either.
