You can call “bs” all you want, but you’re yelling at the messenger. If I understand the situation correctly, you’re using an Amazon service, so Amazon promoting Amazon stuff on that service might count as self-promotion (or whatever the term is) rather than advertisement. The difference being that they’re not being paid by somebody to promote their thing, and just calling out their own services/events.
Note that I’m also not supporting this, I don’t like it, but I’m also not surprised if that’s how that works, and that Amazon would be using it this way.
It definitely didn’t always require a wipe - I think it might be storage encryption by default that was introduced, that made it a requirement, where modifying/replacing system/bootloader components means it can’t decrypt the data anymore.
