Show me some examples because I'd love to see it. I could use a whitepill. From my what I've read they typically tell people to fuck off.
A few big ones I can think of:
1) Allowing AM2R to actually release before sending the C&D. Most people list this as a negative but they were aware of this shit, unofficially, long before release and waited for it to come out anyway even though they were secretly remaking Metroid 2 themselves at the exact same time.
2) Letting the Mother translation continue existing with zero legal threats at all.
3) Actively participating in the Sky Skipper rebuild even though it was done using code that someone had stolen from them. Like, literally stolen as in copied a rom from an arcade machine they owned and kept as a museum piece without permission in violation of contract. This one, in particular, is great for arcade history nerds and is what preservation is really all about.
4) Allowing Project M to exist, publicly, for years even though its fans shit on the dev team constantly. Eventually took it down but I think only because they were modding in 3rd party IP that could have effected relations with certain other companies (*cough* *cough* Capcom.)
5) Running the best internal preservation and cataloging system in gaming for decades.
6) Almost always try to send business to existing partners, even when their output isn't actually good. Have multiple internal teams dedicated to "coaching up" these outside contractors so that even a release from the Dynasty Warriors team will be non-janky and of high quality.
7) Amassed something like half of Japan's 90s era RPG makers into its various second party and subsidiary studios.

Revealed tons of old info, for free, in the old Iwata Asks sections. Allowed Sakurai to reveal stuff like that in his current series of game creation Youtube videos. Openly discuss "failed"/"for testing only" projects like Stage Debut and Sound Factory, despite it being of interest only to hardcore game history nerds.
9) Seemingly intent on remastering everything GCN-era and later, but in a smart way where games will come in and out of availability over time. Allowing them to maintain both access, cultural relevance and, most importantly, sales.
10) Pretty much keep four or five genres alive in the AAA space solely on their own. When's the last AAA kart racer or platformer that isn't from them or a remake?
11) All those Pokemon fan games and Mario kaizos that are out there? You think Nintendo doesn't know about them.
And yes, for the ones of those above that are products, you do have to pay for them. Thats how life works.
