Because RPi is way more mature? Look at the CHIP forums and how many people have problems having the device work correctly. And don't even start on the flashing procedure... Also, RPi is way older. In '12 when it arrived, there were many problems, but it also was nearly alone on the market. When today you have many alternatives that are maybe pricier, but a lot more reliable (Arduino, BeagleBone, Pi..).
