Why the fuck is it so hard for them to part with what they would consider pocket change?
It's not about the money
It's about "fuck you, I do what I want now do what I tell you or I will throw more money than most cities get in their yearly budget in order to ruin everything for everyone"
Just a guess, but when the person you're replying to says "nestle" they mean "the company of nestle, it's employees and all their bullshit" rather than "this specific person from the company" like most people...
I doubt many people are under the illusion that major players in any company are directly involved with astroturfing on websites they don't own.
It's always going to be a low level employee, possibly even an unpaid intern.
