Regarding the stimulus payment, is it true if a spouse doesn’t have an SS# the entire family is disqualified from receiving the payment?

On my Facebook people are saying if a spouse has an ITIN# instead of an SS# the couple can’t receive any stimulus money. That just doesn’t make sense to me. I have yet to see a quote from the actual stimulus that states that.

I don’t doubt the ITIN spouse can’t get counted, but why would the citizen or permanent resident spouse who has an SS# be disqualified?
