“Spying” implies the user doesn’t know about it.
Virtually every platform collects this information, partly as a service to the user, so I don’t think it’s completely ridiculous.
One thing I do appreciate about Nintendo is that it works completely offline so if you don’t want them to have any info about you, you can keep it.
I agree but also very unlikely it would make a difference if they were only sharing from their personal account.
