Schools (at least around here in a pretty good school district) have terrible Wi-Fi, and if the school supports BYOD then the APs are commonly at capacity. It’s much easier to use Ethernet if you want to get some Pis for a classroom, since the teacher can just hook them up to a switch and not have to think about whether the Wi-Fi is good, sharing PSKs (or having every kid log in to 802.1x), making sure that the devices all get on the same subnet so that its easy to communicate with them, etc. And the Pi is aimed at schools, so that is what they will think about. Especially in lower-class areas I wouldn’t be surprised if they don’t have Wi-Fi on the entire campus (although in the US, we have eRate to help with that).
