Re: [EXT] Re: LS from GSMA EIG to W3C

To give some perspective, you should follow this thread [1] at the eIDAS 
ARF. It seems GSMA suddenly woke up and realized they need to be part of 
it. I've given them seven reasons why BBS+ is currently not favored for 
the PID, but they seem not to understand. So I assume they are privacy 
advocates at any cost or they might have a hidden agenda.
