A few centuries? It wasn't until 2006 that the British government gave the Irish language a legal status in Northern Ireland. But, to date there has been no political progress on passing an Irish Language Act there.

This followed the Good Friday Agreement in 1998 with the British government committed to “recognise the importance of respect, understanding and tolerance in relation to linguistic diversity … including the Irish language”.

I'm pretty sure it is owned, just has obstacles still in place by the same people that attempted to force people to stop using it, and succeeded for the most part. The recentness of both of those milestones shows that. It also shows that it is not the same thing as your example.
