I mean, they are two people, and this product just left beta. They certainly need to prioritize. That would be equally true if they'd started with Android.
And it's especially true early in the development of any product, when major decisions are still being made, and even more true when there are sudden bursts of uptake, which can impact infrastructure in unexpected ways, which can then affect architectural decisions about the app.
Trying to do all of that on two platforms simultaneously is almost certainly an unnecessary dilution of effort this early in the development of the product.
That doesn't make Android an afterthought. It just makes it next.
