It's rather suspicious imo that the two titles that were shown to have been just rushed out to try and capitalise on sales (Mr Shifty and NBA Playgrounds) are the ones that are having 'harsh' experiences with Nintendo.
Mr Shifty was a title that the publishers farmed out to a 2 man studio to rush out. When people started complaining they began by denying there were issues, then saying have games like Zelda have issues and people are ok with that etc and only accepted there were issues and admitted fault when enough people started complaining. At times it seemed like they either didn't know what was causing the issues or just didn't want to accept there were issues. This patched was promised several times and then was released after a decent wait. Again, Nintendo were blamed for this delay due to their approval taking much longer due to Golden week. I don't think much of this as it is to be expected that holidays would cause delays. A thread on reddit chronicling a lot of the issues can be found

NBA playgrounds too was rushed out for launch. The devs admitted that they did this because they needed launch day parity to ensure a successful launch, as a delay would have cost sales. They also mentioned that a 2-3 month delay would have been necessary to get full feature parity across platforms, hence why they believed it was more important to get it out there rather than to hold it back. However, when the game initially released they said that online would be ready in a few days. Now, if online was the feature the game is missing, why would it require a delay of 2-3 months but a patch to get feature parity would only take a few days? These things are completely contadictory imo.
I totally believe Nintendo would have some sort of patch size requirement, and I also believe there are hoops to jump through, as you would expect as dodgy patches that cause issues cannot be release. Judging by nintendos past endeavours I also don't doubt that they are a bit behind the times, but I do not believe that this is the issue here. We have two games that were rushed out and not up to scratch and we've had people then trying to frame this as totally not their fault and all the fault of Nintendo
