Yes, it is a value, but it isn't really anything that couldn't be rewritten from scratch in about 30 minutes by a typescript developer.
And it's possible that they aren't even directly using his code, and don't even really know about it beyond an automated system publishing the licenses. Due to the way licensing works, Nintendo could be using OSS library A that they shower their largess upon with free switches, but library A uses library B, which uses library C, which uses safe-buffer. Safe-buffer would still have to have their license published in that manner, but it isn't really clear that nintendo is exploiting that party. Hell, it could even be the case that the author's code is never actually executed on the switch, if for example it was bundled in but is part of a feature that is never called, because Nintendo wanted to use other parts of the same library that happened to include safe-buffer.
By the way, I just checked Nintendo's open source switch library, and there are at least 36,000 copyright notices present in the archive. That's a lot of free switches!
