It may be just a bug. Amazon is to big to do such things on purpose.
There is a valid case to use the cam while Support:
Fraud detection (hehe. Several accounts, but same face. Duked!)
If you need to show something.
Some people, like hearing & speaking disabled, may want to see & be seen for support reasons.
After disabling, is it still possible to use the app? If not, it's a bug. If yes, then start another ticket and ask them that :)
I don't want to have the big 3
ad-network-providers on my phone (ama, Goog, meta) as they're earning money with insights into the users. Because of that, I disabled all official apps on my phone and if I'm in need to use their service, I use my browser. Browsers also allow the most functions, that an app may want. But usually, I'm asked whether I want to allow. The best part, if I do not consent, the website still works as intended (because the main target of a Website is stationary desktop and a lot of computers aren't equipped with a cam. So, no cam, must still work).
So, it's up to you. You have the power of choice. Use it wisely you must (master Yoda, 247 BC)
Still terrifying. Do you have a possibility to apply some kind of a videofilter to hide your face? On Samsung I can blur the background and do some basic effect, if I reconcile properly.
