It's the reason why Madden 20 isn't on Switch. They looked at sales of Madden 18 and Madden 19 on Switch and then made the logical decision to forego a port of Madden 20. Sales numbers don't lie.
I know... I'm not sure how you can read his statement and not facepalm when you actually read what he is saying there.
His logic is that games they put out like Anthem are more likely to get played on the PS4 by users who might also have a Switch, ergo a Switch owner would play rather play their title on the PS4 than on the Switch... but that's not a choice, if a person who owns a Switch wants to check out Anthem then they can't choose to play it on the Switch and must check it elsewhere, that isn't saying that user has a preference to play it on the PS4, the choice simply doesn't exist to play it on the Switch, what this argument overlooks is that there are people who have a Switch, see a title which would fit nicely on the system, while... still owning a PS4 or gaming PC and when the EA title doesn't come to the Switch we think.... "fuck it" and don't buy the product.
This would be like a Gym only offering 12 month subs because they find that none of their customers buy anything other than a 12 month subscription, they instead choose to buy the 12 month option... because... of course, that is the only way to access said Gym, what about all the potential customers this would cost them who are interested in shorter terms? This Gym doesn't care because it's sold enough 12 month subs to keep the lights on, their argument works fine!
Wait until something shakes up EA's business model like when loot boxes have to force a warning label on the box like fags and booze does or when Fifa has to be 18s due to the potential gambling it contains, or when people who rant about EA all year don't have at least 3-4 EA titles bought in that same time period. They'll keep on doing what they're doing regardless.
As others have pointed out in the thread though.... not sure if people have seen the Switch library recently, not having EA Handegg Gambling Simulator 2019 on it isn't really creating a lack of anything to play.
