I can't imagine what's arrogant about it. It's hardly the only reason someone might choose an Android device, but it definitely influences many consumers, and thus the market as a whole.
If someone wants to spend $100 on an unlocked phone, it's not going to be an iPhone. There are entire market segments in some parts of the world that Android basically has 100% market share in, because the cheapest iPhone is still too expensive for mainstream consumers in that market. It's not as much of a factor in the US, but it's still a factor. It's a huge factor in some other parts of the world.
