Ultimately I am down for both options regardless
It isn't though because the original/post point I was making is Nintendo has a (recent)history of such practices and overcharges to boot.. so I am hopeful this business practice doesn't repeat in the next generation.
This only makes sense if you conflate ports and BC. For most of their history, they had both. Recently, they had a new architecture and media so we only had one, and we got more of it to make up for lack of the other. Now, it's looking likely we will have both again.
BTW I'm one of the 7 people that bought all those Wii U games first and TBH kinda wished I hadn't. But at no point did the thought even cross my mind that Nintendo was "charging me for BC" on Switch. They pushed the reset button fully, which sometimes means tearing the bandaid off for a better future. BC on Switch 2 in ARM for Switch 1 games is far more valuable than BC would have been on Switch 1 with Wii U titles -which would never have worked with all my physical disc copies anyway, even if they wanted to just give you the port as "BC" digital, Xbox style. Most people would be in this same boat grabbing most copies of Mario, Zelda and Donkey Kongs on physical.
I don't think it would be smart to market them as "Wii U BC games" like MS does with 360 games anyway. Wii was a tanked brand, and those games didn't get a chance. They just released them on a different/better platform for them to shine, as "Switch Games", and buried the past.
