So if you want to start a new social network site to allow people to publicly share fitness information and routes used by runners, swimmers and cyclists, how would you go about it that would be different from what Strava already does? Strava doesn't collect the data because it can, it's doing so because that's the service it provides. This isn't a case of installing some generic Messenger app and discovering that it also collects and sends to their servers the list of local wifi networks (for which there may be a valid technical reason but it would otherwise be surprising as it's removed from the main objective which is to send messages), it's more like installing a forum app and discovering that your post on the forums can be read by anyone else that accesses the same forum... I get that not all people have the same understanding of how an Internet forum works but that doesn't mean that it's always the website's fault here.
