This is kinda looking for loopholes not recognizing the core reality of the situation. In addition to EV certs having a cost, you likely have to have a DUNS number which is globally unique, and that is a registry which can appropriately attribute you to a given country.

Is there many a hypothetical scenario where you could register a business, get a DUNS number, go through EV verification, be situated in the same country, somehow nobody stops you from registering an additional company called Microsoft?

...Maybe. And after spending a decent amount of money and leaving a massive trail of breadcrumbs to your identity with several different institutions, you will get sued, arrested, or both.

Meanwhile anyone can get a free Let's Encrypt cert for mlcrosoft.cn.
