The first tweet in the exchange was a non-attendee expressing their frustration that the invited bloggers weren't able (or didn't want) to see the inherent conflict of Coca-Cola hosting a nutrition conference for them.
The second was a blogger explaining it's totally cool because Canadian public health icon ParticipACTION and the World Wildlife Fund charity both work with Coca-Cola.
If @ParticipACTION & @WWF are onboard why can't we be? There's a lot of good work being done at @cocacola_ca @emma_willer #koconversations

Innocence by association is not an insignificant return on their investment.
And if you care to see more of why Coca-Cola hosts conferences for bloggers have a peek at these other #KOConversations tweets (just get past the first few from non-attendees that happened after the fact and were actually critical).
