If people are working out where you live using Strava then it is User error! No excuses. Same with any social media. Of course if people are lazy and don't take the time to understand the media they are using then they could be more vulnerable in terms of privacy.
Strava is easy to set up:
1. Ensure Followers have to ask permission first so that you only approve those you know - don't treat it as a fan-base for all to follow.
2. Hide start and finish points.
3. No flyby's.
4. Only start your ride a mile or so from your home. Call it part of the warm-up and don't count it as part of your ride on Strava.
5. Optional extras: Don't ride the same route at the same time every day. Don't post photos. Don't list your bikes on your Profile. (I do post photos and real bike list on my profile but adhere to the stuff above).
Sounds like the sort of advise given to women when they go out
do not wear revealing clothes
go out in pairs
tell someone where you are going
tell someone when you will be back
avoid dark routes
etc etc
although you are right - I am going to review my privacy just in case
wonder if STrava could tell the Police who has been looking at your routes if you have a bike stolen
