I guess this must depend on the specific customer. I consider the primary function to be displaying ebooks, and I don't find getting ebooks at places other than Amazon to be any less easy than getting ebooks from Amazon. Although I suppose there are some people who chose a Kindle over a non-Amazon ereader for the ease of getting ebooks from Amazon, I would not think that most people who are still using older Kindles think the same way you do, especially considering that they already made it impossible for the models without wifi to get ebooks from Amazon last year. But I suppose there's no way to know for sure.

Since a final update available that enables users to use the device as they please would be an acceptable alternative, what would "using the device as they please" mean in this case?

Actually, you can do those things on a hacked Switch, although I have no idea how well Blender and libreoffice would run.

I use my Steam Deck all the time. I hate playing games on a phone, and my computer isn't portable. Even at home sometimes I like to be somewhere other than my computer desk, to play in my yard, or to play a game while I have just a few minutes where I can't really go back to my computer (while I wait for a pot to boil for example). It isn't that much bigger than a GameGear (GameGear was 210mm x 113mm x 38mm, SteamDeck is 298mm x 117mm x 49mm), and is only about 40 grams heavier than a GameGear full of batteries, and I was smaller when GameGear was new, so I don't find it too big.

They ceased service for specific devices (and I would bet there's something in the terms that makes the cessation of services for specific devices NOT a violation of the terms). But it's something to be aware of as many people will want to continue using Amazon's services on other devices.

New ebooks can no longer be purchased directly from Amazon using an old Kindle."

Well, yes, but also, new ebooks can no longer be purchased from Amazon FOR a pre-2013 Kindle, since they did away with the "download & transfer via USB" option on the Amazon site last year.

The primary function is displaying ebooks, which the devices still do perfectly fine. Purchasing ebooks from Amazon is not the primary function, nor is it critical.
