> As the same Prime Video app has to work on Kindle devices, LineageOS/CopperheadOS/other third party ROMs, and on Google Play Android devices, it can’t require Google Play Services.

It can have additional functionality that only works when Google Play Services is available. Plenty of media apps run on Kindle devices as well as branded Android, and support Chromecast on Android but not Kindle.

Now, Amazon probably doesn't want to make an app that has features that work on branded Android but not Kindle, but that is a choice.

That's correct, but looking at how much money Amazon has spent trying to replicate Google's closed APIs on their Android version, I don't think it's unreasonable for them to expect an open protocol at least this time.

Amazon spent billions trying to work around Google's anticompetitive bullshit (something the open source community had to do as well with microG), and I think at least at some point Google should be held responsible for their proprietary bullshit.

Had Google actually open sourced Chromecast, on all sides, you'd have seen much higher adoption.
