--Microsoft, internal document
TECHRIGHTS mentioned quite recently a "controlled opposition" approach which Microsoft uses to infiltrate and subvert panels. Here is a UK government site complaining about what Microsoft is doing:
e aware of our recently re-launched consultation on which we have been soliciting your views since 9th February 2012. One of our first discussion roundtables held on the 4th of April (Competition and European Interaction) was facilitated by Dr Andrew Hopkirk who blogged about the event for Computer Weekly and who was engaged by Cabinet Office as an independent facilitator on a pro-bono basis.
The UK cabinet office washes its dirty laundry in the open. They accuse the facilitator of their controversial round table on open standards, Dr. Hopkirk, of a conflict of interest: an advisory role for an American software manufacturer which is an outspoken opponent of open standard policies.
