Explain then how they are "evading" tax? Every explanation attempted ends up back at "well what they are doing is legal, but they should voluntarily pay more". Just like the linked editorial.

Apple actually has a large reserve for taxes it owes when it repatriates it's foreign profits. It's choosing to legally defer that tax by waiting, just like a private citizen defers taxes by not selling profitable stocks before the end of the year, or by keeping money in their 401K instead of withdrawing it.

Deferral isn't evasion. It's an important legal part of the tax system to incentivize savings.
