I think they are referring to the fact how Fortinet was founded by two Chinese born brothers.

Tho Ken Xie is also a Stanford graduate and has had US citizenship for decades.

Not only that, but them having the bulk of their staff in China.

> not only that

By this logic does it not mean that Google is a Russian/Soviet company? Sergey Brin was born and spent some years in Russia, also Google has staff in Russia(and China in this regard)

He was born there, but he did not remain as a citizen of that country, and not been going back, and forth in line of business.

A situation is different from where a double citizen operates a sales office of a company from his home country

So that we are on a same page, you are stating that any company is de-factor to be considered belonging to country X if: 1) Founder has a double citizenship 2) Has some of the staff in a foreign country 3) Has a sales office in their home country

Is above what you are trying to say?

In this case, the sales office is their main office, and the Chinese "subsidiary" is where the main body of the company really is.
