As your own link states, it's a controversial term and its use is objected to by the Irish Government: https://en.m.wikipedia.org/wiki/British_Isles_naming_dispute

The talk pages and edit history for the Wikipedia article on the British Isles term are interesting. You can see the arguments and edit wars. Much like the insistence on naming the country page for Ireland the "Republic of Ireland' (which is our football team and country descriptor, not the name of the country), I think Wikipedia are on the wrong side of history here, but some editors até vociferous in their objections to change.
