Nintendo, while aggressively litigious, do so to maintain the value and exclusivity of their IP.
Their games also never go on sale, and all sell really well over time, unlike many releases from other publishers.
The result is that Nintendo are able to release a solid cadence of high quality, first party games free of other forms of aggressive monetisation, maintaining the value of the games as art.
I support their prices but most of the lawsuits are bad.
The switch emulator scene did fly too close to the sun, since they were taking donations and pirating games on day 1. Most places wait until the console generation is over before getting to work on software preservation
