Anyone tested Tor in China recently? Back when I was making regular business trips there, I not only tested and reported bugs, but I shared it with many locals who were interested in what an open Internet experience was like. (Sadly, wanting facebook access as the #1 reason, a reliable gmail/google was #2)
Over the years I watched a fascinating arms race unfold. From it working out of the box, to needing a bridge, then obfs, obfs2, obfs3, obfs4... On my last trip, even obfs4 wasn't working.
