We have considered alternative single board computers, but there is nothing on the market that matches the price/performance ratio.
The IoT market is constantly in flux and this statement is no longer true. I don't bring this up to take away anything from the fine work the RPF is doing, but there are commercially available boards which compete with the ZeroW. Here's one example:

I've used various boards from OrangePi and they're certainly not as well supported as RPi's boards, but they do work. In general, these boards support the Linux I/O drivers for I2C, GPIO and SPI, so you have standard ways of talking to peripherals. If you're project currently depends on some Python wrapper for a RPi-specific API (e.g. PIGPIO), then you'll have to do a little coding to adapt it.
