edit: Sorry, I'm pretty drunk. to answer your more complex query yes the calls I've gotten have all been obviously non commercial. I do agree with the sentiment that safeguards need be carefully considered. like some proof you're blind maybe before you can be a requester for image analysis. I hear your cynicism but the app has been around a long time and it is beyond just pure unbridled mutual aid. it feels great to help and the blind get to temporarily have an eyed friend on hand, on demand. it's a wonderful app, download it and hope you get a call!
I say lucky because they were such good people with such a great mission. Hans (founder) and Christian (co-founder) were really, really fun to get to spend ~10 weeks with.
The new CEO is fairly recent so I can't vouch either way for him. Hans and Christian were an absolute joy with incredible hearts.
