So is "Word". I would be equally surprised if Google released word processing software called "Android Word".
If I created a word processor called "Mike's Word Processor" I'm pretty sure I'd be good.
This reminds me of the Microsoft vs MikeRowSoft case [1], where Microsoft took legal action against a high schooler for a domain that was phonetically similar to their company name.
Which is clearly a different trademark despite the fact that they share one word that is key to describing the product's functionality. Might as well compare Burger King and Whataburger.
