For those unfamiliar with the topic, these two chips are by and far the most common wifi chips for DIY and are also very common in IoT devices. Due to cheap price ($2—$5 depending on the model) and very low barrier to entry technically, these devices are both very popular as well as very wide spread in those two categories.
These chips are the first hits for searches such as "Arduino wifi module", "breadboard wifi", "IoT wifi module", and many, many more as they're the downright easiest way to add wifi to something that doesn't have it out of the box.
I'm not sure how applicable these attack vectors are in the real world, but they affect a very large number of devices for sure.
