I don't know enough to argue for one side or the other, but I think the provided link could be misleading (not necessarily intentionally)

Fixing our corrupt system is the real solution.
For example: If US company X makes $100B in foreign income in 2017 and repatriates that income in 2019, they will book 0% tax paid in 2017.
Similarly, if X pays income tax to a foreign government they will receive credits for tax already paid - but due to accounting practices the US government will not count the credits when publishing the effective tax rate of X. That last point isn't germane to this particular article but it is something behind many of the 'Look at the low tax rate of X' articles you will see around.
Thus a corporation domiciled in California is still paying a corp tax rate about as high as any in the world.
