What? Umber is just a preposition, it doesn't has nazi overtones. The fact that it's grammatically incorrect is probably a plus, because it's then less likely to be confused.
"über" does not always have nazi overtones but as with many other similiar words in the german language it is definitely tainted with nazi overtones, which are very obviously present depending on the context in which a word is used.
If you use "über" to describe something as better in some way, nazi overtones are very obviously present and if you name a company Uber, it's definitely implied that you're better than the alternatives.

Wasn't this the point of the name?
Where I live people use über often and it means pretty much what it means in German and has no Nazi connotations. (Of course most of our German ancestors moved here long before WWI)
Of course it's the point but in precisely in this context it has a nazi overtones because this is how the nazis used it see "Übermensch" or "Deutschland über alles".
"Deutschland, Deutschland über alles, über alles in der Welt..." is the beginning of the first verse of the national anthem that has now been banned, although mostly because it refers to borders that Germany now does not have anymore.
