US washing powders norms and US standard washing cycles are quite different than the European ones. US powders usually contains more detergents, and the washing machines use hot tap water. EU norms forbid to use machines for hot tap water, and force to use low amount of detergents, so washing is done at lower temperature and with lower amount of detergents, but takes much longer.
That might be an explanation for this mystery, as the pigments used for coloring fabrics in EU are tested according to EU washing norms.

Likewise, I've had no issue with this. Though it's usually washed on a low temperature which might be a factor?

Hullo.
I have discovered that the Wikimania 2016 T-shirt bleeds its lovely color quite liberally, so I recommend you hand-wash it or wash it separately for the first few times, until it stops, if you don't want your other clothes to gain a new hue. :)
