Thinks buying more servers can fix a bad patch
Those games would indeed not be exclusive, which is also irrelevant.
Nowhere does the article mention the game has to be exclusive, in fact it counts several games which are not exclusive.
Again, this list has been created by someone just looking at Wikipedia. And that's why it's not accurate. The author didn't care if a game was exclusive or crossbuy or anything like that.
Edit: To give an example, for PS3 he's counted Minecraft as a first party million seller. Are you willing to admit the list is inaccurate?
The article title literally says "Nintendo Switch", which is 1 console of itself. It is not that hard to see that they are implying it has to be an exclusive in some extend. There's no need to dumb down their explanation when that's that explicit and common sense.
Those games are exclusive in their context of being able to play on that console if you buy from there.
