It would be like Apple paying off forum sites to do something like that, graying out Android users in any public discourse. Android phones are more popular in African American communities, so Apple is already doing segregation-like stuff with these hard to read text bubbles.
That's the most convoluted reason to call someone racist I've heard of in a long time.
A better analogy would be HN greying comments that were posted from any device that wasn't manufactured by Apple.
