Just because Strava says the data is pseudonymised doesn't mean that it
really is.  (Spoiler alert: it probably isn't.)

There's a terrific paper by Arvind Narayanan of Princeton that's become
one of the must-reads in this area:

        A Precautionary Approach to Big Data Privacy
        http://randomwalker.info/publications/precautionary.pdf

And as Cory Doctorow explains here:

        An incredibly important paper on whether data can ever be
"anonymized" and how we should handle release of large data-sets
        https://boingboing.net/2018/02/01/high-dimensional-data.html

and as I've been saying for years, anonymization is HARD.  The field
is rife with examples of smart people who've made credible tries and
have still failed miserably.
