Unfortunately this is the end state for many gig for hire apps, uber, tasktabbit etc, I think food delivery is probably the worst because the customer does not interact with the contractor at all, compared to other apps, so you can’t even hear if the driver is getting ripped off on their end.
The tip stealing thing felt very similar to one thing I noticed last night during NYE was certain friends who used uber more had to pay higher for the same rides as me who never uses the app. There’s so much data singling both drivers and consumers out to maximize returns, it’s crazy
