It is hard to decide on one meaning. It depends not only on which part of the world you come from, but also on one’s personal attitude.
The western world uses the three wise monkeys for people who deal with evil or impropriety with turning a blind eye on it. How ironic, if you think about the amount of people ignoring hate speech and discrimination online. The Web is not as an anonymous robot space anymore, as it may has been some decades ago. You are dealing with real personalities, bullying real people, spoiling real lives. Even if the first meaning of the three wise monkeys does not suit you, do not let the second become your reality.
