Considering, well according to someone here anyway, it was on the Amiga format CD every month, I doubt there was any license agreement at all. The ROM chip/image was probably the legal point.
It all comes down to 'fair use', but that term is very broad. For example, you could buy a toaster, dismantle it, and use the outer shell as an ornament. It's your toaster to do that with. However, there's a 'right and wrong' issue here.
Personally, I would consider it right/fine/ok that you could use your legally obtained ROM image (from your own amiga) and legally obtained WB disks (again from your own Amiga) and use them in UAE. You're using what you bought for your own purposes.
I would also consider it right/fine/ok to keep an infinite number of copies of the WB disks, provided you kept them somewhere where other people can't get hold of them.
However, for example, Microsoft has a problem with people having more than one backup of the software after installation, let alone the installation media. Most business users have an issue with this, say for example servers with tape backup. Microsoft considers it illegal to make a copy of the install CD.
Microsoft also considers it illegal for someone to buy a copy of Windows, use it on one machine, wipe that machine completely and sell it, then use the same copy of Windows to install onto another machine. Why? Because having to buy a new copy of Windows for a replacement machine means more money for them. Also according to MS it is illegal to sell a machine without an operating system on it.
