> Why are they calling it GMI instead of UBI now?*
Because that's what it is? If it were UBI then it would be labeled UBI instead.
> after taxes are considered there's not any difference between UBI and GMI.
Mathematically that is true, but there is still a significant human difference. Consider a case where you have a loss of income. With UBI, the money will just show up at the usual interval to keep you going. With GMI, money will not show up until you go through the arduous process of notifying authorities that you are now eligible. And if you've ever dealt with people who manage these kinds of things before, you know they don't operate on an instant basis, so you could be going quite some time before the support finally shows up.
