In the last decade, they’ve been aggressively pursuing emulator hobbyists and “making deals they couldn’t refuse” (Yuzu).
Recently, they started offering a “soundtrack” app as part of the benefits of Nintendo Online where you can listen to music from their first-party games. I see this as an administrative move to demonstrate active marketing of their properties, to delay their copyrights lapse (similar to Disney bringing Steamboat Willy to try to preserve a 100-year-old copyright).
Also see the Switch 2 tech demo app being sold rather than included. Can you imagine if Microsoft charged for the Windows XP tour, or Apple for the Tips app?
There is not one single aspect I can point to that makes you say “gotcha”, but micro-aggressions against fans seem to be adding up and tipping the scale away from a company that gives warm, fuzzy feelings deserving of fandom.
