I think it's a valid concern, look at how many originally open-source Android APIs and frameworks Google has pushed out in favor of their proprietary one's. Similar concerns I've seen voiced is there being a inseparable integration with Google services, like how Google has pushed Gapps dependency onto Android, but now baked into the OS-level.
