Problem is that Google can easily bulldoze their way into any market just by creating their own service and then putting at the top as a widget. They did that with flights as you can see here and they were sued for it 8 years ago already, although I think that case is still active.
On the other hand I don't think it's OK to put limits on their creativity and efforts to improve user experience. If they want to make a topic specific widget, why not?
If you type 123+321 it will say 444 first, then display search results. That's how it should be, they don't have to protect the "123+321" keyword market.
