As an Irish person I can't help feeling a frisson of satisfaction.
But as a developer, this is just asking for confusion, especially since the Irish flag is already confusing enough.
I mean, we could have a beautiful white harp on a green background representing Irish culture. The Welsh got a dragon...
But no, it's a political statement from 120 years ago represented in three boring vertical stripes, just like everyone else's flag. It's identical (ok, mirrored) to the Ivory cost flag. It's the same three colors as the India flag, rotated 90 degrees, which itself is very similar to the Niger flag. And if you squint, or just don't know your flags well, it could easily be the Italian flag. It's a terrible choice to represent a language.
