I'm not sure the generalization is accurate. Most of us can remember the 'i before e' rule we were taught as kids, but the English language is a celebrated mess of borrowed words and guidelines masquerading as rules. It is admittedly confusing for native and non-native speakers alike, but if we throw a reliance on spell check into the mix, which does little to help with spelling a person's name, we just create more opportunity for degradation.
That said, it should be a pretty hard rule when writing about a person to, at the very least, check to make sure you spelled their name correctly.
