I think that's one of the important parts of the article; corporate management is either unwilling or completely incapable of differentiating between average and exceptional talent and often doesn't reward the latter properly. This means the only option for exceptional talent to be justly rewarded is to continually jump ship.

IMO that's terrible business practice, especially in software development.

I wouldn't even say talent, necessarily. Every year you work somewhere is another notch against all the jobs that want 10+ years iOS experience. But all industries are like that, and want more years of experience, and often will pay you that 20% difference just because you have worked in the industry longer.
