into your own history - you have not had an apostrophe "as part of our culture for a thousand years" at all.
The apostrophe in your name is actually a fairly recent (in historical terms) substitute for the correct Irish Ó which means 'grandson' as in Ó Mháille (now O'Malley). It is you, the Irish, who stopped using the correct spelling of your names, not the "nameless programmers who are too ignorant or crass to realize it's importance"
Nobody on the planet can use an apostrophe in an email address - it has nothing whatever to do with SKY, as you seem to think.
I suggest that you get off your high horse, stop referring to the 'cultural crassness' of the English, and learn a little about your own cultural crassness in misunderstanding the origins of the spelling of your own name.
