A lot of great art was originally sponsored/commissioned by wealthy corporate benefactors (for example the Catholic Church and nobility in 15th century Italy).
I think it's important that the beholder/public in general is aware of the providence of a piece of art, yet I doubt banning corporate sponsorship of art would be a net positive for society.
Damn, I was planning on using Vault eventually. This attitude towards security gives me pause about put all my secrets into it. Is there any alternatives?
