Oh, come on. As someone who's developed for both platforms, and worked with plenty of other devs (who ought to neither be ignorant nor prejudicial about the situation at hand as their job depends upon it) make quips of this sort all the time. Android is near-exclusively the target of their mirth.
This leaves irrelevance, perhaps, but given the context of this thread I'd argue it's not that either.
The beauty of Hacker News is that it isn't filled up with irrelevant quips that tend to polarise discussions. We can actually learn from each other despite our differences.
