Yes and no. I think I remember hearing about a license before that would require anybody that forks your project to create a PR for any changes they make.

While this wouldn't prevent a company from using your project, but it would at least force them to pass on any of their changes.

...it would deter them, which is what your original question was asking. Preventing and deterring are two completely different things.
