This letter (PDF here) sent to Derek Yach on November 16, 2017 by Clive Bates and co-signed by six other tobacco control advocates is important because it spells out requirements to make the Foundation credible despite its funding by Philip Morris International.
The 7 signatories are: Clive Bates, David Abrams, Jean-François Etter, Lynn T. Kozlowski, Thomas J. Miller, Raymond S. Niaura, David T. Sweanor.
Derek Yach replied on January 9th 2018 (PDF here) but, as far as I know there was no follow up after this exchange of letters.
