Per DAS charter feedback: Mozilla has significant concerns about the inclusion of the Network Information API in the charter (as a specification to potentially adopt from the WICG) — Mozilla's public position is that this API is "harmful" to the Web as the information that it provides is unreliable and, at the same time, open to privacy abuses. As we have stated publicly, we believe it is "better that sites use methods that dynamically adapt to available bandwidth, as that is more accurate and likely to be applicable in the moment". Or, alternatively, use newer declarative solutions, such as "lazy loading" images and alike.
