Google invested in KaiOS to get its services pre-installed[1]. Soon, you won't be able to get a phone without Google, unless it's targeted at Chinese market or is made by Apple.

I agree with your concern, but I can report there are alternatives:
* SailfishOS (version 3 is due), successor or Maemo/MeeGo, uses Mer and official ports have Android emulation [1]
* LineageOS (with or without MicroG) [2] [3]
* UBPorts, a community project continuation of Ubuntu Touch [4]
* PureOS [5]
And then there's CopperheadOS though it has imploded last time I checked, and PostmarketOS which is a nice alternative if all else isn't updated anymore or otherwise fails.
I'm using LineageOS with MicroG on a FP2. If anyone got questions about that, shoot.

But also to your bubble. SailfishOS targets upcoming markets such as India and Russia. So no, you won't find those on Amazon. I wouldn't use Amazon as the sole holy grail in this regard. Also, you can buy a Sony Xperia X and buy a SailfishOS license for it. You can run in on a device such as a FP2.
In order for mostly-dumb phone like that to be useful for me there are a few small things I'd need to sort out via software, but they won't allow it.
Stallman was right etc.
