The Ruby creator is Japanese but if you want to start using it today, you don't even have to know who Matz is. The website with the documentation is in English and translated to quite a number of other languages.

It really is not the fair comparison and I get what the parent was refering to.

Ruby is developed in a English community. People communicate in English. That makes a difference.

In the Wa community, you can speak English and we can understand English. Likewise, others must have the right to speak Chinese. This is fair to both Chinese and English users.

It is more about how the project is developed and maintained.

For example, Vue is founded by a Chinese. But the development happens in English. Issue tracker, RFC, code comments, all in English. Therefore, people around the world would know what direction the project is heading towards.
