Should Artists Collaborate with Businesses?

Many artists view all things related to money with a great deal of suspicion. Much of the discussion revolves around anxieties related to a loss of integrity; the fear of being seen as 'selling out'.

Some artists welcome the opportunity to work with businesses, such as Takashi Murakami, Andy Warhol, Jeff Koons, etc. However, a number of artists and writers I have spoken to have expressed dismay about artists who are too quick to accept the financial rewards that come with such relationships.

What are your thoughts?
