You can call Android fork Android. Even Nokia/Microsoft does. It does have Android experience as it is using Android for the hell. It doesn't have Google Play, but remember Google Play has not even existed in original Android, and Google Play is NOT part of the Android, but something else, don't want to bother with details...
It always helps the discussion if you read the articles to which I've provided links. From the Wikipedia article about Android:
"Google Mobile Services software, along with Android trademarks, can only be licensed by hardware manufacturers for devices that meet Google's compatibility standards contained within Android Compatibility Definition Document. Thus, forks of Android that make major changes to the OS itself, such as Amazon's Fire OS (used on the Kindle Fire line of tablets, and oriented towards Amazon services), Microsoft's briefly supported Nokia X Software Platform (a fork used by the Nokia X family and oriented toward Microsoft services, having its support ending with Nokia X2) or other forks which exclude Google apps due to the general unavailability of Google service in that country and licensing fees (such as in China), do not include any of Google's non-free components, are incompatible with apps that require them, and must ship with their own proprietary software marketplace instead of Google Play Store. In 2014, Google also began to require that all Android devices which license the Google Mobile Services software display a prominent "Powered by Android" logo on their boot screens.
Members of the Open Handset Alliance, which include the majority of Android OEMs, are also contractually forbidden from producing Android devices based on forks of the OS; in 2012, Acer Inc. was forced by Google to halt production on a device powered by Alibaba Group's Aliyun OS with threats of removal from the OHA, as Google deemed the platform to be an incompatible version of Android. Alibaba Group defended the allegations, arguing that the OS was a distinct platform from Android (primarily using HTML5 apps), but incorporated portions of Android's platform to allow backwards compatibility with third-party Android software. Indeed, the devices did ship with an application store which offered Android apps; however, the majority of them were pirated."
Microsoft can refer to the Android OS when indicating that an app (such as OneNote) is available for Android devices. But as the article to which Xandros9 linked (Google’s iron grip on Android: Controlling open source by any means necessary | Ars Technica), don't buy an Amazon Fire phone and expect to get Google Play or other Google Mobile Apps.
The point of my OP is to emphasize that Google has decided to go head-to-head with Microsoft as an OS developer. They aren't going to do anything to level the playing field between Android and WP devices (including an official YouTube app for WP). Since they own YouTube, they can make it an Android exclusive if they choose to. And while they may make YouTube available on Xbox (is that an app or just a website wrapper?), they don't sell gaming consoles, do they?
I can appreciate their reasoning for requiring all Android-licensed hardware manufacturers to ship devices with all the Google services installed and requiring that certain things be visible on the home screen or immediately accessible with a single tap. They want all Android phone buyers to have phones that look like one another out of the box. Microsoft does the same thing with their 3rd-party hardware manufacturers for all their OSs.
All I'm suggesting here is that if you want Google services, go buy a Google phone.
