I’m using a Samsung phone. A lot of the software on my phone (especially the software I paid for with the phone) is made in South Korea. I don’t pay for a lot of apps, but the apps I paid for were made by developers from France, Spain, Japan, Austria/Germany, and the US, one each.

My computers are running Windows, sure, but my most used software would be Firefox, built by people from all over the world. Second place would probably belong to JetBrains Rider, made by a company headquartered in Czechia.
