Freud would say...

I have two questions about the highlighted sentence in the following context. 1. Does "Freud would say" here mean that "Freud says", i.e Freud has said such a thing, or does it mean "If Freud wanted to say something in this regard he would say" i.e he has not said such a thing. 2. Does " need to unleash" mean "want to unleash" and " attempt to unleash" or "have to unleash"? Context: The contemporary artists discussed in this chapter have employed the mask in one form or another, and in doing so have been able to freely pursue personal, political and artistic issues through disguise, and with humour. It is through disguise that the artist enables the release of his or her inhibitions and true feelings and the emergence of ideas into new forms that would otherwise not be possible. Freud would say that artists who deal with matters of disguise need to unleash what they are repressing, yet there may be some prohibitions or cultural taboos against certain forms of behaviour or thinking. The disguise permits the expression of such ideas in a socially acceptable way, and with some distance for the artists.
