Well, I'd imagine that before returning the value through their API they could just check that if the number is negative, then add 2^32 to it, which would make it look like an unsigned 32 bit integer.

But isn't that exactly what they were trying to not do as their problem was the api users and not their internal use?

It was definitely a problem with their database but I suppose it's possible that the customers were also expecting 32 bit signed ints.

In most languages that support differently sized integer types and/or unsigned integer types, you wouldn’t have to check, but can just apply the appropriate modulo or bit operation on all values.
