hardly anyone uses iOS.
I keep harping on this point because you are doing wishful thinking. The numbers for iOS usage in Western Europe are around 32%. That's far from "hardly anyone". In the UK is over 50%, in Australia it's over 60%.
If you care about keeping in contact with friends and family, you'll be bound to find someone on iOS. What are you going to do, tell them to get a new phone just so they can participate in the family group chat?
At this point I almost think not supporting crappy Apple products is a feature.
Yeah, those grapes really are sour...
