Personal responsibility
How about people have some?
If you are sending data to the cloud, then think long and hard about whether it's a good idea and how private it is.
Especially potentially personally identifiable data.
.. from the strava users I know a lot of it is about "oneupmanship" e.g. showing off to others how quickly they completed cycling challenge x etc.
Though I'm the sort of person where the only occasion I know how long a run took (time & distance) is when I do a park run (or similar) that is a known distance & my time is officially logged.
