Yeah but that’s like saying people with liberal arts degrees do well in marketing and hr.
I wouldn't build a tech business out of entirely physicists, but there aren't that many physicists anyway.
This is not all that uncommon in businesses that are not "pure software" plays. If a product or service involves domain knowledge outside of programming, you always need to keep one or two people around who are experts in it, or people who are willing to actually develop that knowledge, which is often what physicists do. I am the keeper of "how it actually works" for a number of product lines.
What I don't know is how I fare alongside CS'ists on payday, because I simply don't know. Even within the software department, there are some people with non CS education.
