Why no upgrade option for people who still have Xbox Ones?

Appreciate the heads up but I did know about this but this is actually part of the issue in my eyes. We shouldn't have to spend $90 to get both versions when he would inevitably have to spend another $300 at the MINIMUM for a series S digital. And that's if he can even get one because of Scalpers. Other games come out with a free upgrade or a $5 upgrade but a whole $30?? and that's with EA Play. Another $5 Dollars.
