Using Google's android is not, but you could get amazon, or whatever. It's part of the ecosystem, if you buy into Amazon's you get their store, if you buy into Google's you get their's. If you want neither, you have to figure that out, or a new company needs to handle that situation.

Even Google's android is viable to use without Google Account.

I've used a (company-issued) Sony phone for two years with in a such way, that the only account on the phone was for our Exchange, with built-in E-mail, Calendar, Contacts apps. Granted, the Play Store was not available, Youtube and Maps didn't work, but they were not the reason why I had that phone.

A huge part of the value for users is the google ecosystem.
