Fair enough, it does make sense that they will maximise their profits where they can, I'm just saying that it (the app not the website) refuses to work unless you provide it a full scope of literally every permission available. Maybe it has more to do with attestation, and verifying that you are not a scammer, than stealing and selling data?
Ahh, my time to apologise for my assumptions. I'm browser on PC/laptop first and rarely use a phone and never for Amazon. I also rock Linux on everything that I can, so my experience will obviously be different on "PC" too.
It really is not about attestation etc, I'm afraid. Its all about maximising profitability.
If you use a walled garden friendly device then you will be frisked inappropriately at every opportunity.
Just ease of use on a small screen really. I don't use it too much anymore anyway, I'm in Australia, so Amazon's not as big here as it is in the US. We mainly use Ali-Express or Temu, because those apps deliver from China, which is close and more convenient for here, relative to the US.
