FWIW Chromium also ships this API on Android and ChromeOS: <https://chromium.googlesource.com/chromium/src/+blame/e1f453c8038dd60f17847dc37603c64835f9d865/content/child/runtime_features.cc#51>. It seems that they ship both the type and typechange events: <https://chromium.googlesource.com/chromium/src/+blame/e1f453c8038dd60f17847dc37603c64835f9d865/third_party/WebKit/Source/modules/netinfo/NetworkInformation.idl>. FWIW I was one of the people who were involved in the discussions around this for Firefox OS. From what I remember, the argument for shipping this API was that web developers have been asking for this for years, and they are basically happy to know the distinction between cellular data and other transports, and infer whether the connection "costs money". On Android at least native apps also use the same crude measure. I think there was also an argument around the lines of asking this being so common that a subset of users who actually do have paid cellular data plans are used to rely on this distinction. The limitations of this API and how little meaning it is actually conveying to the developers was generally well understood, but the counter argument for that would be that it's pretty clear we're never going to be able to give the app accurate information unless we know about what servers they want to talk to, and perhaps other load characteristics, and even then we'd probably need to measure the bandwidth, which could cost money, defeating the whole purpose; and with that in mind, it's better to expose something now rather than nothing. I have to say I personally don't find the last argument reasonable for downlinkMax, but I can understand it for type.
