Found the guy who's difficult to work with...

Seriously though, every company has had to deal with one of these people sooner or later. The cost to team morale always outweighs the talent of the difficult developer. Let them go, let them learn, and hope they fix their act at the next company. It always hurts to throw away talent.

It's also possible that the company is decidedly mediocre but has a strong culture of having people who all think the same way on the team. Smart person sees this and is frustrated but doesn't have managerial authority to make improvements.

Different cultures have different expectations of the relationship between employer, colleagues and the employee. Guessing op is from a place where being right is more important than everyone being on the same page but being wrong.
