They're sending multiple people, just not the CEO. It's logistically impossible for a CEO to be in every country at every government's whim, and also run their company. Shouldn't a company be allowed to choose who represents it legally?
If they've got enough people to send in their place, then they also have enough people to run the company while they do the things like this.
It's not like it's just any country's whim, it's a group of G7 countries conveniently meeting next door.
If every single little country was calling on them all the time, then yeah maybe, but this seems like one of those "pick and choose" situation where you should send the CEO and Founder.

So legal authority is determined by the size of the nation? Or the number? They either can or cannot compel him to do so, regardless of size or number.
If there's anyone who will simply not be disrupted AT ALL by this kind of visit, it's the CEO of a $500bn company who has the resources of a small nation at his disposal. Hell, it's even practically the same time zone.
