[liberationtech] question about browser/Gmail subject line / browser history exposure

Fri Jul 6 13:04:27 PDT 2012

Hi LibTechers,

This is David Sullivan at the Global Network Initiative. I just wanted to
let you know that we're looking into this issue and will get back to this
list shortly, both with clarification on how this type of issue fits into
the company commitments as part of GNI, as well as thoughts on next steps
on this specific issue with these companies. Thanks Katrin and Robert for
flagging it.

Best,
David
