It amazes me how many people think how unimportant real, signifcant third party support from companies like EA is for long-term success of a console's life.
Yes I know, "Fuck EA, they're cancer, worst company in America"... EA brings in $5 billion a year. That's an enormous consumer base. Their games matter to the gaming community whether you like it or not.
There are millions of people out there that won't consider a console that doesn't have games like Call of Duty, Madden, Grand Theft Auto, and Assassin's Creed. How many Switches could Nintendo sell if they had these franchises on their platform?
What's even more amazing is anyone thinking EA is important to the long term success of any Nintendo platform.
You're right that EA games absolutely do matter and are a very big part of the gaming community but overall they have had very little relevance to the Nintendo fanbase for 30+ years.
Wii U literally launched with 3 of those 4 franchises you listed and went on to be their worst selling console ever, now obviously those games didnt cause it to fail but they certainly didnt help it in any meaningful way.
I've said it dozens of times on these forums, the AAA/mainstream/hardcore western titles you are referring to are a welcome addition but not necessary for Nintendo platforms to succeed.
You could make the argument that Nintendo needed those games 20+ years ago to prevent Playstation/Xbox from gaining such a strong foothold but that type of software is synonymous with those brands at this point.
The likes of EA, Activision, Ubisoft, etc do not need Nintendo to make their AAA titles succeed and Nintendo does not need those AAA titles to make their platforms succeed, its really as simple as that.
When the herd loses its way, the shepard must kill the bull that leads them astray.
