First, a quick aside. I was surprised to see this, way to go Medium! http://i.imgur.com/XwJRGKV.png

Now onto an actual on-topic comment:

This comes at no real surprise to me. I'm certain Coke isn't the only soda company to be paying people off. Let alone the only company. It's nice the author researched enough into the people and the not-so-subtle advertising going on; but really... anyone with public outreach is a potential advertiser and if they're mentioning a name-brand product, you'd likely win a bet that they received a donation in some form or another.

The problem should be that these sorts of implicit bribes are legal in the first place.
