As a European IT professional and a Kagi subscriber, I get my information from and contribute my knowledge to the same sources as you do. I don't know why I would bother to look something up in my native language when there is much more information available in English, the lingua franca of the (Western) world. I don't even read Wikipedia in my own language, unless the subject is better covered.
I’m also European and subscribe to Kagi. One feature I really like is that I can specifically make a local search by adding a bang with the country, like !fr or !es.
