Take a step back. A more objective fact is that most CEOs/CTOs reached their positions not because they optimized the two-year role jumping. It's either from a long tenure with a company or from founding a successful startup and got acquired.
Very rarely can one reach VP level by simply jumping around. One's past loyalty becomes a non-trivial factor for positions at that level.
My 2 cents.
"Stop sabotaging your career with long stints".
Very few developers are CEOs/CTOs. Even fewer have founded a successful startup or gotten acquired. Very rarely can one get a promotion or a raise by staying at one job for more than 3 years. The bigger your network is the more likely you will get an interesting job offer at a company where your past loyalty is irrelevant but your personal connection is.
My 2 cents.
I guess another way to phrase my understanding is that: if your (possibly unattainable) career ambition is to reach CTO level, you should know that in the past, very rarely is that achieved with 2-year job jumping.
If your goal is to get steady compensation growth, probably job switching can give you that. And that is also probably what most of people should do anyways.
