Yeah this is really pushing a gray area. Looking at it one way Red Hat is not obligated to do business with anyone, and if they stop doing business with a customer that customer still has all the rights granted to them by licenses of software they have already received, so in that sense Red Hat hasn't restricted the customer's rights in that software. However, on the other hand refusing to do business with someone in retaliation for exercising the rights granted by the licenses smells a lot like a restriction.
