It's not a directly comparable situation. Tizen is its own thing, while Kindle is an Android fork, which doesn't meet the terms of Google Play licensing -- it wasn't like Google took away access; it never granted it in the first place, which is the same situation with many other tablet makers. Manufacturers make Windows phones and Android phones at the same time without problems. Tizen's been around for many years without being able to break into the market (under various other names), and Samsung's Android customizations are what people complain about most. Also, it's a lot more work to maintain your own operating system and services, so it remains to be seen whether it will ever go anywhere. I don't think Google's wrath will be a problem, it will be the lack of apps and such.
